Kai Whittaker

Kai Thorsten Whittaker (born 10 April 1985 in Baden-Baden) is a German politician of the Christian Democratic Union (CDU) and an economist. He has been a member of the Bundestag since October 2013, holding the direct mandate for constituency 273, Rastatt, in Baden-Württemberg. The 18th Bundestag, the legislative term in which he entered parliament, held its constituting session on 22 October 2013.

He passed the Abitur in 2004 at the Markgraf-Ludwig-Gymnasium in Baden-Baden and then did civilian service at the municipal hospital of Klinikum Mittelbaden. From 2005 to 2008 he studied economics and management at the University of Bristol, graduating with a Bachelor of Science, and from 2009 to 2010 he took a Master of Science in European political economy at the London School of Economics. Before his election he worked as an assistant to management at LEONI AG in 2008–09 and at Herrenknecht AG in Schwanau from 2011 to 2013.

The Federal Returning Officer's tables for the constituency record a CDU first-vote share of 53.5 percent in 2013 (77,850 votes), 44.1 percent in 2017 (68,259) and 33.2 percent in 2021 (50,988), the elections across which he held the direct mandate. At the 2025 federal election the same office listed Kai Thorsten Whittaker of the CDU as elected with 63,116 first votes (38.9 percent), ahead of Alexander Arpaschi of the Alternative for Germany on 22.2 percent, with turnout at 81.6 percent.

In the 21st Bundestag he is a full member of the Committee on Labour and Social Affairs and of the Committee on European Union Affairs, a deputy member of the Foreign Affairs Committee and of the Franco-German Parliamentary Assembly, and chair of the parliamentary group for the United States. From 2017 to 2021 he was the CDU/CSU group's spokesman on the Parliamentary Advisory Council for Sustainable Development. He has chaired the CDU district association in Baden-Baden since 2022 and, since 2024, has been an assessor on the federal board of the Christian Democratic Employees' Association (CDA).

In November 2025 Der Spiegel described him as deputy chair of the workers' group in the CDU/CSU parliamentary party and reported that he sided with Chancellor Friedrich Merz against the Junge Union in a dispute over the coalition's pension package. On 30 June 2017, in the Bundestag vote that opened marriage to same-sex couples, he was among the Union members recorded as voting yes; the bill passed by 393 votes to 226, with four abstentions, after the parliamentary whip had been lifted.

Early life and education

Family and childhood

Kai Whittaker was born on 10 April 1985 in Baden-Baden, in Baden-Württemberg. In a curriculum vitae on his website he wrote that he was the son of Nigel, a master joiner (Schreinermeister) from Britain who later worked in sports management, and of Gabriele, from Villingen, now part of Villingen-Schwenningen, a trained secretary who later worked as a freelance sales representative and whose family largely remained there; that he grew up with a younger sister, Leigh, in Winden, a village in the municipality of Sinzheim, near Baden-Baden; and that close relatives remained in the English Midlands and near London.

A 2024 profile in the Bundestag magazine Das Parlament described the father as a trained carpenter (Tischler) from Britain and the mother as a sports teacher and a secretary. It reported that he grew up in modest, lower-middle-class circumstances in which household spending was watched closely, and that politics was not a standing subject at home, although watching the ARD evening news programme Tagesschau was a ritual.

In a profile published on 19 April 2014, the Hessische/Niedersächsische Allgemeine reported that Nigel Whittaker, then manager of Golfclub Gut Wissmannshof in Speele, had been born in England and had lived in Germany since 1979. It reported that he had first settled in Hamburg and then moved to Baden-Baden, where he married and had two children; that he was a trained Kaufmann who had come to golf-club management by chance; and that Speele was his fifth posting in the sport. The newspaper described his son as a member of the Bundestag and his daughter, then 25, as a professional golfer, and reported that the children had learned about their English background from him.

Schooling and civilian service

Whittaker took his Abitur in 2004 at the Markgraf-Ludwig-Gymnasium in Baden-Baden. Das Parlament reported that as a pupil he was class spokesperson (Klassensprecher) and wrote for the youth supplement of the Badisches Tagblatt, including a sharp comment on the condition of the school toilets, which the profile presented as a possible start to his own political activity.

From 2004 to 2005 he performed Zivildienst, Germany's civilian alternative to compulsory military service, at the Stadtklinik Baden-Baden, operated by Klinikum Mittelbaden GmbH. The Bundestag notes that the biographical dates it publishes are those supplied by the member.

University studies

From 2005 to 2008 he studied at the University of Bristol and graduated with a Bachelor of Science in Economics and Management. Das Parlament reported that the course combined economics and business administration, and that while a student in Bristol he spent his earnings on flights back to Germany. The same profile said that, until he left Baden-Baden's municipal council in 2009, he missed only one of its meetings.

In 2009–10 he completed a Master of Science in European Political Economy at the London School of Economics and Political Science. A Baden-Baden news profile likewise records economics studies at Bristol and at the London School of Economics. He has stated that his master's thesis examined the fiscal discipline of all eurozone parties between 1992 and 2008.

Career before parliament

Before he took his seat in the Bundestag in October 2013, Kai Whittaker’s recorded employment outside local politics was two spells as an assistant to company management, with a master’s degree between them. The parliament’s biography, which the Bundestag says rests on members’ own information, lists him as Assistent der Geschäftsleitung at LEONI AG from 2008 to 2009 and at Herrenknecht AG from 2011 to 2013, and gives his occupation as economist (M.Sc.).

Journalism

A profile by Jan Rübel in the Bundestag newspaper Das Parlament on 29 October 2024 is the published account of any writing for a newspaper. Rübel wrote that Whittaker, then a class speaker, contributed to the youth supplement of the Badisches Tagblatt and commented sharply there on the condition of the school toilets, which the profile treats as a possible first step into political activity. The article places that writing before 2004, the year he became the youngest member of the Baden-Baden city council. The Bundestag biography does not record a newsroom job, a traineeship, or later freelance reporting.

Corporate posts

After a Bachelor of Science in Economics and Management at the University of Bristol, completed in 2008, Whittaker spent 2008–2009 as assistant to the management at Leoni AG. His own CV places that post in Roth, near Nuremberg. Leoni is a Nuremberg-based automotive supplier of wiring harnesses; Handelsblatt has also described it as a maker of cables and wiring systems with a production site in Roth, where harnesses were bundled. The published biographies give the job title and do not describe the work.

He then took a Master of Science in European Political Economy at the London School of Economics in London, finishing in 2010. On his website he wrote that the thesis examined the budgetary discipline of all euro-area parties between 1992 and 2008.

From 2011 to 2013 he again worked as assistant to the management, this time at Herrenknecht AG. In the Bundestag’s register of employment before membership the firm is given as Herrenknecht AG, Schwanau. Martin Herrenknecht, an engineer from Allmannsweier, built the company as a maker of large boring machines, with the main plant beside that town; the machines are used for mechanized tunnelling, including the road tunnel under the Bosphorus and tunnels through cities and mountain ranges. The 2024 Das Parlament profile shortens those years to a master’s degree in London, the Herrenknecht assistantship and a successful candidacy in 2013, and does not mention Leoni. The Bundestag dates membership from October 2013, and the company posts are not listed as continuing after he entered parliament.

Party and local offices

Whittaker's party offices have been held in Baden-Baden and in regional bodies of the Christian Democratic Union of Germany (CDU) in Baden-Württemberg. The Junge Union (JU) is the independent youth association of the CDU and the Christian Social Union in Bavaria; its own rules allow membership from the age of 14 until 35, whether or not the member also belongs to either party. The Christlich-Demokratische Arbeitnehmerschaft (CDA) describes itself as an association inside the CDU and as the party's social-policy wing, oriented toward employees and their families.

Junge Union and municipal council

Whittaker has written that he was politically active in the Junge Union and the CDU from 1999. His Bundestag biography lists him as district chairman (Kreisvorsitzender) of the Junge Union Baden-Baden from 2001 to 2010, and as a member of the city's youth council (Jugendgemeinderat) from 2001 to 2004. In 2004, at the age of 19, he was elected to Baden-Baden's city council (Stadtrat); the same biography gives the mandate as running until 2009. On an earlier version of his website he wrote that this made him the council's youngest member, and that between 2004 and 2009 he sat on the school committee and the youth-welfare committee. He has also said that he stood again in 2009 and was not re-elected. The Bundestag entry records the end of the council term but does not describe that result.

CDU and CDA roles

The Bundestag biography lists him as deputy district chairman of the CDU Baden-Baden from 2011 to 2022 and as district chairman from 2022. Before the 2022 vote, the Badische Neueste Nachrichten reported that he was the only declared candidate to lead the district association. At the district conference on the evening of 5 May 2022 in the Löwensaal in Lichtental, he was the sole candidate to succeed Ralf Müller, who did not stand again. The local news site goodnews4.de reported that 61 members attended and that 56 voted yes, three voted no and three abstained. The district association's website continues to name him as chairman.

The same Bundestag biography says he has been a member of the executive of the CDU Bezirksverband Nordbaden since 2015. Party accounts of the regional congress in Hockenheim, published on 1 November 2021, list him as the association's secretary (Schriftführer) on the executive chosen when Moritz Oppelt became regional chairman. A CDU Nordbaden release on the congress of 9 November 2024 in St. Leon-Rot, which re-elected Oppelt, again names Whittaker as secretary, and the association's board page still lists him as Bezirksschriftführer.

In the CDA, delegates at the 40th federal congress in Weimar on 14 and 15 September 2024 were told that Whittaker was among those newly elected to the federal executive. The board published after the 41st federal congress in Marburg in 2026 still lists him as an assessor (Beisitzer); that entry also describes him as chairman of CDA Nordbaden. The Bundestag biography records him as deputy chairman of the CDA Bezirksverband Nordbaden from 2024. A report by CDA Mannheim on the subsequent Nordbaden district conference said that Karin Möhle handed over the chair after 16 years and that Whittaker was elected unanimously. The association's calendar placed that conference on 31 January 2026 at the Bildungshaus St. Bernhard in Rastatt. CDA Nordbaden's own board page lists him as chairman, with Uwe Terhorst, Gerald Hock and Steffen Hofmann as deputy chairs.

Bundestag elections

2013 entry

Bundestag constituency 273, named Rastatt, comprises the urban district of Baden-Baden and the district of Rastatt in Baden-Württemberg. In Germany's personalized proportional system the first vote chooses a constituency candidate and the second a party list. Through 2021, the leading first-vote candidate took the constituency seat outright.

On 4 March 2013 the Christian Democratic Union associations of Baden-Baden and Rastatt nominated Kai Whittaker, then 27 and the youngest of five contenders, to succeed Peter Götz. Nearly 600 members voted in the Badner Halle, and Whittaker won on a third ballot. Götz, a CDU member of the Bundestag from 1990, wrote that his mandate would end with the September election.

At the federal election of 22 September 2013 the CDU received 77,850 first votes, 53.5 percent of valid votes and 5.4 points above its 2009 share. Südwestrundfunk later identified Whittaker as the candidate who passed half the first votes, and Abgeordnetenwatch records the seat as his constituency mandate at 53.5 percent. The Social Democratic Party was second, with 33,482 votes (23.0 percent). Alliance 90/The Greens took 8.4 percent, the Alternative for Germany 4.8 percent, Die Linke 3.5 percent and the Free Democratic Party 3.1 percent. Turnout was 71.4 percent of 207,555 eligible voters. On second votes the CDU led with 49.2 percent, ahead of the SPD on 20.6 percent. Gabriele Katzmarek, recorded as the SPD candidate in Rastatt with that same 23.0 percent, entered on the Baden-Württemberg list in 12th place rather than by winning the constituency.

Re-elections in 2017 and 2021

Südwestrundfunk has reported that CDU constituency candidates had won Rastatt at every federal election since 1949. In 2017 Whittaker was returned with 68,259 first votes, 44.1 percent, 9.4 points below the CDU share of 2013. Die Welt, using provisional figures published on 25 September 2017, named Katzmarek second on 19.0 percent, Joachim Kuhs (AfD) on 12.2 percent, Manuel Hummel (Greens) on 10.9 percent and Rolf Pilarski (FDP) on 7.2 percent. The final official totals for those parties were 29,486, 18,849, 16,954 and 11,150 votes. Turnout was 76.1 percent of 206,484 eligible voters. Second votes split more widely: CDU 37.9 percent, SPD 17.0, AfD 12.7, FDP 11.5 and Greens 11.4. Katzmarek again sat via the SPD state list, in 11th place; Whittaker's seat remained the constituency mandate.

In 2021 his first-vote share fell to 50,988 (33.2 percent), 10.9 points below 2017, still ahead of the SPD on 34,847 (22.7 percent). Südwestrundfunk named the main candidates as Whittaker, Katzmarek, Thomas Gönner for the Greens, the physician Sven Gehrke for the FDP and Verena Bäuerle for the AfD. The final first-vote shares were 13.0 percent (19,962) for the Greens, 11.6 percent (17,764) for the FDP and 10.7 percent (16,455) for the AfD. Turnout was 75.8 percent of 204,890 eligible voters. On second votes the CDU lead narrowed to 27.0 percent, against the SPD on 23.7, the Greens on 14.3 and the FDP on 13.8. Abgeordnetenwatch again lists Whittaker's mandate as the constituency seat, and Katzmarek's personal vote as 34,847 — the SPD first-vote total — with list place 11.

2025 federal election

The federal election was held on 23 February 2025. It kept two votes, but a constituency leader was seated only under Zweitstimmendeckung: in each Land, a party's leading constituency candidates were ranked by first-vote share and filled only up to the seats its second votes had earned there. Remaining seats came from the closed state list, and overhang no longer enlarged the Bundestag.

In Rastatt, 163,973 of 200,964 eligible voters cast ballots, a turnout of 81.6 percent. The final result named Kai Thorsten Whittaker (CDU) as elected in the constituency with 63,116 first votes, 38.9 percent, 5.7 points above 2021. Alexander Arpaschi (AfD) was runner-up with 36,075 votes, 22.2 percent, up 11.5 points. The SPD fell to 24,569 (15.1 percent) and the Greens to 18,274 (11.2 percent). The SWR graphic above uses the broadcaster's election-night count, which put the CDU at 38.8 percent. A Baden-Baden report that night named the other leading candidates as Lukas Hornung (SPD), Frank Brede (Greens), Lothar Tatzik (Die Linke) and Dominic Frank (FDP), at shares matching the final party lines. On second votes the CDU led with 54,348 (33.4 percent), then the AfD on 36,771 (22.6), the SPD on 23,553 (14.5), the Greens on 17,673 (10.8) and Bündnis Sahra Wagenknecht on 6,681 (4.1). SWR again described the seat as having stayed with the CDU since 1949.

Whittaker was not on the CDU Baden-Württemberg list of 59 candidates announced on 3 February 2025. The seat recorded for him is the constituency mandate, listed among the Land's constituency winners at 38.9 percent; his Bundestag biography states the same mandate for Wahlkreis 273. Arpaschi, 11th on the AfD state list, was elected from that list. Hornung was 20th on the SPD list and Brede 35th on the Green list. Among members elected from those lists, the highest SPD place was 13 and the highest Green place was 11.

Parliamentary roles

Committees

In the Bundestag, a parliamentary group (Fraktion) prepares the chamber’s decisions and holds rights, such as introducing bills, that members lack on their own. Forming one takes at least five percent of members, from one party or from parties that do not compete in any Land—the basis on which the Christian Democratic Union and the Christian Social Union sit as one CDU/CSU group. Committees prepare plenary decisions. Groups name the full members and the substitutes who stand in for them, in proportion to group strength. Remits usually follow the federal ministries, but every Bundestag must have committees on defence, foreign affairs, European Union affairs and petitions.

Whittaker has been a full member of the Committee on Labour and Social Affairs since he entered parliament in October 2013. In the 18th Bundestag (2013–2017) he was also a deputy member of the Finance Committee, the Committee on Education, Research and Technology Assessment, and the Digital Agenda Committee. In the 19th (2017–2021) he was a deputy on the Digital Agenda Committee and the Committee on Transport and Digital Infrastructure, and in the 20th (2021–2025) on the Committee on Housing, Urban Development, Building and Municipalities. In the 21st Bundestag he is a full member of the labour committee and of the Committee on European Union Affairs, and a deputy member of the Foreign Affairs Committee.

Earlier offices and rapporteurships

From 2017 to 2021 he was Obmann of the CDU/CSU group in the Parliamentary Advisory Council for Sustainable Development, listed apart from his ordinary membership. The office is not the chair: when the council was constituted in April 2018, Andreas Lenz (CDU/CSU) was elected to lead it, and Whittaker was one of six members from the group. The council, which is not tied to one ministry, accompanies the national sustainability strategy and recommends on medium- and long-term planning.

Inside the CDU/CSU group he sits on the working groups for European Union affairs and for labour and social affairs, on the local-government working community, in the circle for small and medium-sized business, and on the Arbeitnehmergruppe. That body is an internal association of the parliamentary group, not a Bundestag committee, oriented to employees and their families. On 20 May 2025 it elected its board for the 21st term, with Whittaker one of several deputy chairs; on 19 November 2025 Der Spiegel called him its Vizechef.

Groups also name rapporteurs for bills and subjects in committee. In the 18th Bundestag Whittaker was the CDU/CSU rapporteur for Hartz IV until the group withdrew that responsibility in November 2014. In March 2024 the Christian Democratic Employees’ Association described him as the rapporteur who had substantially shaped the CDU paper on a “Neue Grundsicherung”, a proposed recasting of basic support for jobseekers.

Interparliamentary groups

In the 21st Bundestag Whittaker chairs the Parlamentariergruppe USA, the all-party group for relations with the United States. As chair he led a delegation to Washington, D.C., Atlanta and Miami from 27 September 2026 into early October, with members from several groups. The programme covered transatlantic relations and economic, defence, security and digital policy, including the approaching congressional elections.

Parlamentariergruppen are all-party associations, renewed each term, for contact with parliaments abroad. The rules commentary distinguishes them from committees and from a Gruppe too small to be a Fraktion. In the 21st term, 47 groups cover about 180 countries. They do not pass bills or treaties; the chamber describes the work as dialogue, and a member may join up to three.

He is also a deputy member of the Franco-German Parliamentary Assembly. It has 100 members, 50 from the Bundestag and 50 from the National Assembly of France, under the Franco-German parliamentary agreement adopted by the National Assembly on 11 March 2019 and by the Bundestag on 20 March 2019.

Labour and welfare policy

Basic income support

Whittaker, a CDU labour-market specialist, argued for repairing Hartz IV, the jobseekers' basic income from Chancellor Gerhard Schröder's Agenda 2010, rather than abolishing it. On Deutschlandfunk on 28 March 2018 he said unemployment had fallen from five million to under 2.5 million, yet measures were failing a core of 900,000 long-term unemployed, of whom, he said, about half had no qualification and half could barely speak German. After SPD chair Andrea Nahles backed an exit, he told the Frankfurter Allgemeine Zeitung in November 2018 that the party wanted to rebuild the welfare state arbitrarily, while the CDU would not "sell the public castles in the air." He called instead for a "fundamental renovation" so that work would pay and lead out of the benefit.

On 14 February 2019 Die Zeit, Der Spiegel and the FAZ reported a five-point paper of his against SPD plans for fewer sanctions, longer unemployment insurance for older workers and more qualification. People under 40 "must start a vocational training." The first €200 of monthly earnings would be deducted in full; above that, 40 percent would be disregarded, up to €1,200 for single people and €1,500 for families. Zeit said €100 jobs would then not pay—against rules that left only the first €100 free and withdrew 80 cents of each further euro—and linked the design to Andreas Peichl of the ifo Institute. He also proposed flat-rate housing and heating, lump sums for extras such as equipment for pregnant women, and a global budget for job centres. Abolishing sanctions was not in the paper. CDU leader Annegret Kramp-Karrenbauer told the broadcaster Welt that the ideas were still only his.

He was later a CDU/CSU rapporteur, with Hülya Düber and the SPD's Jens Peick and Daniela Rump, on the bill that turned Bürgergeld back into Grundsicherung. The labour committee adopted the amended draft on 4 March 2026 against the Alternative for Germany, Alliance 90/The Greens and Die Linke; the Bundestag passed it the next day by 320 votes to 268. It stressed placement in work, ended the grace period on savings, capped reimbursable housing costs and allowed the standard allowance to be removed entirely after a staged procedure. He pointed to powers for the Federal Employment Agency against fraud, liability for employers using undeclared work, and integration from the day a claim is filed, and said a later step should let people keep more earnings and flat-rate housing costs. In October 2025 he told Deutschlandfunk that placement could still yield the Union's €5 billion saving, against figures from Labour Minister Bärbel Bas of €86 million and €69 million over two years. On 22 October 2026 the station said the scheme, in force since July, had apparently not yet eased the federal budget.

Activation, sanctions and job centres

In 2018 he put a caseworker's time at about 40 minutes a month per person and wanted language support, longer training and debt advice in one place. Berlin mayor Michael Müller's plan for public jobs near the minimum wage was, he said, wage dumping. Sanctions, he argued, matched a duty to attend and apply for work, while the standard rate should not rise so far that wages no longer left more net income. Zeit reported that the 2019 paper would have cut caseloads from 1:128 to 1:75, the ratio then used for under-25s.

In January 2026 SWR quoted him: a cooperation plan could not arise "if people do not talk to each other," and nobody could be placed "if he permanently withdraws." SWR described a 30 percent cut for three months for refusing reasonable work, and a possible total cut after a hearing. Greens and Die Linke called that too harsh, and the AfD too soft. On 5 March he cited hearing evidence from Stefan Graaf that, without a response to persistent non-cooperation, advice fails, and said the Greens in effect wanted an unconditional basic income. He called for a "red card" where sick notes were used to skip appointments. The act also let a centre order a medical assessment where mental illness was suspected, and required parents to be available for work from the end of a child's 14th month.

Procurement and the digitization of work

On 23 March 2017, on a Green motion on "Work 4.0," Whittaker called the exchange a fear debate: exploitation, blurred boundaries, intensified work and constant availability were "four fears and zero solutions." Digitization had already arrived, he said—online booking, networked machines and, citing the German Economic Institute, more than half of Germans working online. From the labour ministry's white paper he argued that people felt more productive, not pressed, and that crowd- and click-work, 4.2 percent of the IT sector, was not mass impoverishment; more than half of the low-skilled, he said, expected easier physical work.

Jobs, he said, would increasingly mean several employers and mixed teams. He wanted working-time rules to allow a split day of office work, family time and a later shift from home, programming in schools as in Estonia, and training incentives before unemployment rather than the SPD proposal ALG Q, which waited until job loss. Klaus Ernst of Die Linke replied that choosing one's hours was not the same on a machine as in management, and that without legal limits shift work would clash with family life and push wages down.

Pension policy

Funded-pension proposals

In June 2021 Christian Democratic Union MP Kai Whittaker proposed Kinder-Rentengeld: €4,000 paid by the state at birth into a public equity fund, available only at retirement. He told Der Spiegel that he had largely drafted the previous autumn's CDU specialists' paper on a funded pillar inside the statutory pension. The Social Democratic Party, Alliance 90/The Greens and the Free Democratic Party were proposing state funds as well, the FDP — like the CDU specialists — with about a tenth of contributions invested plus €1,000 at birth rather than €4,000. From an average nominal DAX return of 8 percent over 50 years, or 6 percent after inflation, he said €4,000 could become about €200,000 in today's purchasing power and a little more than €900 a month over 18 statistical years of retirement, "roughly the amount that prevents old-age poverty". He put the annual cost at €3.2 billion for about 800,000 births, in a low-cost fund under the pension insurance or the Deutsche Bundesbank. Der Spiegel noted that the grant would raise tax subsidies while the contributor-to-pensioner ratio worsened, and that the first payouts would come only around 2090. Whittaker agreed that it would not solve the immediate problem, and said the pension could be changed only in many small steps.

A February 2022 Spiegel essay with MEP Dennis Radtke repeated Kinder-Rentengeld as a funded pillar that, in their view, would relieve the pension fund, and argued that social contributions could not stay at 40 percent of wages if old age was to remain dignified. The €4,000 grant was not enacted. On 16 October 2026 the Bundestag instead passed, with CDU/CSU and SPD votes, a Frühstartrente of €10 a month from age six to 18 for children born from 2020, into a private depot or a Bundesbank equity portfolio, intended to take effect on 1 January 2027. Der Spiegel reported a Finance Ministry projection, excluding inflation and later tax, of more than €50,000 by retirement from the €1,440 of state contributions.

The 2025 pension package

In November 2025, as deputy chair of the employees' group in the CDU/CSU parliamentary party, Whittaker backed Chancellor Friedrich Merz against Union critics of the coalition pension bill. The visible lead of a paywalled Spiegel report had him contradicting the Junge Union with the line that the chancellor was right. He told the Tagesspiegel that he could not follow the Junge Gruppe: the hold-line until 2031 was already law, and the group was demanding a new rule absent from the coalition agreement. About 18 of its members opposed the draft over a feared lock-in past 2031 and costs they put at €120 billion. Whittaker warned that if pensions moved too close to basic assistance the Federal Constitutional Court could "blow the entire pension up in our faces", dismissed longer working lives or a lower level alone as "Pille-Palle", and called for a funded second pillar with a minimum share of income. Employers' president Rainer Dulger, citing the pension-insurance report, said the coalition could not afford the package.

The Bundestag passed the bill on 5 December 2025 by 318 votes to 224, with 53 abstentions, two above the chancellor's majority of 316. Seven of 208 Union members voted no, including Johannes Winkel and Pascal Reddig. Whittaker wrote that he voted yes. Bundesrat consent was not required. It holds the pension level — a standard pension after 45 average-earning years, as a share of average pay — at a minimum of 48 percent through 1 July 2031, and about one point higher afterwards than without the line. Tagesschau cited the pension-insurance report for a federal cost of €122 billion through 2039 for that safeguard. From 2027, Mütterrente III gives three years' credit for children born before 1992, about €20 a month per child for roughly ten million parents, mostly women; from 2026 the Aktivrente makes up to €2,000 a month of continued social-insurance wages tax-free. Extra federal spending was put at about €10 billion a year from 2028 and about €18.4 billion in 2039. The Frühstartrente was not in the bill.

On his website Whittaker argued that the changes followed the coalition agreement, that from 2031 the sustainability factor would resume from 48 percent rather than a lower hypothetical path, and that €120 billion for 2031–2040 was about 1.5 percent of pension spending to 2040, with a 2029 review and tax rather than contribution finance. Merz called the result the start of pension policy and promised a broader reform in 2026.

Other political positions

Marriage equality and intra-party alignment

On 30 June 2017 the Bundestag voted to open civil marriage to same-sex couples. Chancellor Angela Merkel had called the question a matter of conscience (Gewissensentscheidung), and discipline in the CDU/CSU was lifted. Of 630 members, 623 voted: 393 in favour, 226 against and four abstentions, all from the Union. Welt recorded 75 Union yes votes and 225 no votes; Merkel voted no, and Kai Whittaker was on the yes list. The Social Democratic Party, with Alliance 90/The Greens and Die Linke, put a Bundesrat bill on the agenda once she treated the issue as one of conscience, which Der Spiegel called a breach of coalition custom.

In the race to succeed Annegret Kramp-Karrenbauer as CDU chair, Whittaker joined the steering team of Norbert Röttgen. In December 2020 he told n-tv there could be neither a simple continuation, which would only administer crises, nor a total break with existing policy; Röttgen, he said, could mark a new departure more clearly than the other candidates and gather both the liberal and the more conservative wings. At the first fully digital party congress, on 16 January 2021, Röttgen missed the runoff. Secretary-general Paul Ziemiak reported 991 second-round votes, 521 for Armin Laschet and 466 for Friedrich Merz, with four abstentions; because the congress was online, that tally still needed a postal ballot carrying only Laschet's name.

Europe, the United States and sustainability

Whittaker is a full member of the Bundestag committee on European Union affairs and chairs the parliament's group for the United States. In January 2026, while President Donald Trump linked further tariffs to opposition over Greenland, he told rbb Inforadio that Europe was not powerless but not yet fully able to defend itself. Heavy military spending in Germany and Europe would, he said, still leave the United States necessary for two to four years. He urged trade deals, including Mercosur and agreements with India and others, and said Europe could "show its teeth" by questioning how openly it financed the US federal budget.

From 2017 to 2021 he was CDU/CSU spokesman (Obmann) on the Parliamentary Advisory Council for Sustainable Development, a cross-cutting body that checks bills against economic, social and ecological criteria beyond a single term. In June 2019 he told taz that a paper from the Union's Klimakreis, which he dated to 2013, should commit the party to a grüne Null — carbon neutrality by a price rather than bans — without gilets jaunes-style unrest, lost jobs or what he called a sermon of renunciation. He called Green warnings scaremongering; taz also reported that he and Thomas Heilmann had started a group of about a dozen deputies on more ambitious proposals.

On 16 March 2021 n-tv published an appeal by 30 CDU deputies, including Whittaker and Röttgen, titled "Politik für eine grüne Null". They contrasted a remaining national aim of cutting greenhouse gases at least 80 percent by 2050 from 1990 with the EU target of climate neutrality by then, and said the Union, having adopted a grüne Null in 2019, should pair it with the balanced-budget schwarze Null. They called the new €25-a-tonne price on transport and heating too low, and proposed replacing overlapping energy taxes and subsidies by 2025 with a higher carbon price, with leakage protection and "clever rules" instead of further bans.

Public disputes

The 2014 rapporteur dispute

In November 2014 the CDU/CSU group in the Bundestag took the Hartz IV brief away from Kai Whittaker. Bild reported on 13 November that, the previous Tuesday, he had lost the rapporteurship after his paper “Arbeitsmarktpolitik 2020 – Schritte in die Zukunft” reached the press without faction clearance; the Frankfurter Allgemeine Zeitung had written about it the Friday before. It proposed bonuses for long-term unemployed people who tried especially hard to find work, and an end to one-euro jobs, which it said did not improve chances on the regular labour market. The group had treated the text as one member’s private reflections, and sources told Bild the removal was a penalty, above all because the bonuses conflicted with the line against softening benefit sanctions. The reports did not quote Whittaker. A spokeswoman would not confirm the step; she said he remained closely involved in labour-market instruments and worked with Karl Schiewerling, spokesman of the Union working group on labour and social affairs, while Bild wrote that he was no longer to speak in public on the subject.

The 2020 demonstration

On Saturday 6 June 2020, during the COVID-19 pandemic, police counted about 15,000 people at an anti-racism demonstration on Berlin’s Alexanderplatz. The Berliner Kurier reported that the crowd stood packed together, many of them masked, and that police ended the rally early because the square was full. The Junge Union in Rastatt accused Whittaker, who had attended the Black Lives Matter demonstration, of “massive irresponsibility”, citing social-media images as proof he had broken the rules then in force; the organisers, that report said, were mainly left-leaning. The Badische Neueste Nachrichten reported that the youth wing had publicly denied he was fit for a Bundestag mandate. He did not answer a written enquiry from goodnews4 that Monday. The outlet’s next story was headlined as a withdrawal of the press statement, while spokesman Kilian Heid said part of the district executive still distanced itself from him for not keeping the distancing rules.

The Mittelbaden hospital and local media

On 29 June 2025 Baden-Baden voted on whether to overturn council resolutions of 25 November 2024 and to approve a new central hospital only if the city were its site. The published count, with all 60 reports in, was 7,514 yes (45.06 percent) and 9,161 no (54.94 percent); 16,720 of 41,892 people entitled to vote took part (39.91 percent). Under the Baden-Württemberg municipal code the majority of valid votes decides the question only if it is also at least 20 percent of those entitled to vote; the no votes cleared that mark, and the city record stated that the question had been answered no. SWR reported that the initiative “Ja! Zum Klinikstandort Baden-Baden” had wanted the mayor to oppose a Rastatt site, and that planning for a hospital of about 660 beds, at about €700 million, could continue at the Münchfeldsee in Rastatt. A later report said the vote had delayed the project by at least a year, with opening then expected in 2034, though Landrat Christian Dusch said it remained inside the financial buffer.

On 23 June Whittaker, chairman of the CDU district association in Baden-Baden, published a guest commentary urging a no. He wrote that Münchfeld had already been chosen jointly with the district of Rastatt, that a yes could push Rastatt out of the joint hospital and leave Baden-Baden with a smaller clinic and no state or federal building grants, and that most staff, especially at the Balg hospital, wanted the planned building. Martin Ernst of the Freie Bürger für Baden-Baden, who favoured a Baden-Baden site, told SWR he was disappointed and that the city’s finances meant it could scarcely afford a stake at all. On abgeordnetenwatch.de, where his profile has continued to show an answer rate of zero, the 2021 Baden-Württemberg grades gave him none of 22 questions and the mark ungenügend; in 2023 he answered one of nine (11 percent), and in 2025 none of ten.

Personal life

Citizenship and family

Kai Thorsten Whittaker was born on 10 April 1985 in Baden-Baden. The Federal Returning Officer recorded that full name for the Christian Democratic Union (CDU) candidate elected in constituency 273 (Rastatt) at the 2025 Bundestag election. The Bundestag biography, which the parliament states is based on members' own information, gives the same date and place of birth and records that he is married, without naming a spouse.

On a curriculum vitae published on his website and preserved in an August 2016 Internet Archive capture, Whittaker wrote that he was the son of Nigel and Gabriele and grew up with a younger sister, Leigh, in Sinzheim-Winden. He described his father as coming from Great Britain, a trained master joiner (Schreinermeister) who later worked in sports management, with close relatives still in the Midlands and near London. His mother, he wrote, came from Villingen, where much of her family still lived; after training as a secretary she was then working as a freelance sales representative.

The Bundestag biography does not state a second nationality. On 15 September 2013 a question on abgeordnetenwatch.de, from a user identified as Henrik E., asserted that Whittaker held citizenship of both Germany and Britain. The writer contrasted that claim with what he called the CDU's categorical rejection of dual citizenship and asked whether Whittaker would give up a British passport if elected or, if not, break the party whip to support dual citizenship. The page still marks the answer as outstanding.

The Badische Neueste Nachrichten reported on 26 June 2025 that the CDU member of the Bundestag from Baden-Baden had married his partner, Ediana Ramirez, in his hometown.

Religion and disclosed activities

In the same self-reported Bundestag biography, Whittaker gives his religious affiliation as Protestant (evangelisch). The biography also lists membership of the Verein zur Pflege der Städtepartnerschaften Baden-Baden e.V.

Under the parliament's rules on registrable interests, the disclosure published on that biography page contains two entries: his employment before he became a member, as assistant to the management (Assistent der Geschäftsleitung) at Herrenknecht AG in Schwanau, and the office of treasurer (Schatzmeister) of the Partnerschaftsverein Baden-Baden, in Baden-Baden. The page does not attach an income band to either entry and does not list a separate paid activity during the mandate. The association, which also uses the short name Städtepartnerschaftsverein, states that it was founded on 2 July 1987 as a charitable body to maintain Baden-Baden's town partnerships through personal contacts between local residents and people in the partner towns.
