# PPP’s Oh Se-hoon holds Seoul as Lee’s Democratic Party falls short in the capital Date: 2026 ## The fact On 3 June 2026, the same local-election day the DP won 12 of 16 metropolitan posts, incumbent Seoul mayor [Oh Se-hoon](/people/oh-se-hoon) of the People Power Party defeated the DP candidate (about 49.22 to 48.07 percent). Pre-election surveys had favoured the DP. ## Context Lee had endorsed the DP Seoul candidate. Neighbouring 12-of-16 print is the gain twin the same day. He did not sit as NEC. A capital loss is still ordinary local contest, remaining later party-leadership fight named. Local 12-of-16 the same day is the gain twin. Han premiership 1 July and Kim Min-seok’s later DP leadership are children. The President of the Republic of Korea is head of state and of the executive, appoints the prime minister with [National Assembly](/organizations/national-assembly) consent, and commands the armed forces. The National Assembly enacts statutes. The Bank of Korea sets the policy rate. Courts, including the Supreme Court and Constitutional Court, judge. Chaebol boards, US Forces Korea, and provincial governments share later series. A Seongnam mayoral youth dividend or debt moratorium is not a 2025 statute. A criminal case must be stored with exact charge and judgment status — an allegation, indictment, first-instance finding, appellate acquittal, Supreme Court remand, or Article 84 stay is not a completed conviction if appealed, overturned, or pending. He did not author Yoon Suk Yeol’s 3 December 2024 martial-law decree. ## Evidence and sources National Election Commission of South Korea carries the official instrument or communique. The New York Times records the same dated act independently. ## Significance The path is [political polarization](/drivers/political-polarization): a completed capital retention by the opposition after a national DP local sweep. ## What is established and what is not Established: 3 June 2026 Oh Se-hoon Seoul win, independently reported. Not established: a unique later 2028 Assembly coefficient from that Wednesday, or that the 12-of-16 print was thereby erased. What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions. The date is the date of this instrument, not a licence to back-date every later harm or benefit. The DP candidate lost. Lee had backed the DP line. NEC certified.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies PPP’s Oh Se-hoon holds Seoul as Lee’s Democratic Party falls short in the capital, not a later speech about PPP’s Oh Se-hoon holds Seoul as Lee’s Democratic Party falls short in the capital. Co-authors and later implementers named in Context remain on the file. PPP’s Oh Se-hoon holds Seoul as Lee’s Democratic Party falls short in the capital on 2026-06-03 is not a licence to treat every later National Election Commission of South Korea communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average PPP’s Oh Se-hoon holds Seoul as Lee’s Democratic Party falls short in the capital into a personality. The contribution described on this Person row is limited to Voters in Seoul chose Oh. The DP candidate lost. Lee had backed the DP line. NEC certified. That limit is the alternative to treating office-holding as authorship of every later series. ## People - Lee Jae Myung: https://factrail.ai/people/lee-jae-myung ## Drivers - Political Polarization: https://factrail.ai/drivers/political-polarization - Democratic Resilience: https://factrail.ai/drivers/democratic-resilience ## Sources - https://www.nytimes.com/2026/06/04/world/asia/south-korea-seoul-mayor-elections.html - https://www.nec.go.kr/site/eng/main.do ## Methodology https://factrail.ai/methodology Canonical: https://factrail.ai/facts/kr-lee-seoul-loss-2026
