# Keir Starmer resigns as Prime Minister; Andy Burnham takes office

Date: 2026

## The fact

On 20 July 2026 Keir Starmer delivered a resignation statement, informed King Charles III, and left office. [Andy Burnham](/people/andy-burnham), already Labour leader, was asked to form a government and kissed hands.

## Context

Labour MPs had forced a leadership change after local-election losses, U-turns, and scandals. Burnham had been confirmed Labour leader on 17 July. A governing party can change its leader without a general election. Starmer’s resignation is a constitutional act he performed. He is not the author of Burnham’s Downing Street speech or of later sentencing pauses. The King appointed the successor.

The 2024 appointment is a different date. Keep the resignation separate from every later SI.

The Prime Minister of the United Kingdom is First Lord of the Treasury and chairs Cabinet. He does not enact statutes alone. Parliament enacts; courts review; the Home Office, DWP, HMT, MoJ, DESNZ and NESO implement. After 20 July 2026 he is a backbench MP for Holborn and St Pancras, not the author of Andy Burnham’s instruments. Office-holding is not authorship of every later welfare series. Allegation is not a completed judgment.

## Evidence and sources

Royal Household carries the official instrument or communique. Associated Press records the same dated act independently.

## Significance

The path is political polarisation and democratic procedure: a completed mid-term replacement after a party revolt is lawful and is also a stability shock. Procedure holding is stored on the appointment side; polarisation is the welfare reading used here.

## What is established and what is not

Established: Starmer resigned and Burnham kissed hands on 20 July 2026 after a Labour leadership change.

Not established: that the resignation authored Burnham’s later reviews, or a unique gilt-rate coefficient from the Palace hour.

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 King appointed Burnham. Labour MPs had changed the leader. Burnham is the successor, not a co-author of 2024 SIs.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Keir Starmer resigns as Prime Minister; Andy Burnham takes office, not a later speech about Keir Starmer resigns as Prime Minister; Andy Burnham takes office.

Co-authors and later implementers named in Context remain on the file. Keir Starmer resigns as Prime Minister; Andy Burnham takes office on 2026-07-20 is not a licence to treat every later Royal Household 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 Keir Starmer resigns as Prime Minister; Andy Burnham takes office into a personality. The contribution described on this Person row is limited to He resigned. The King appointed Burnham. Labour MPs had changed the leader. Burnham is the successor, not a co-author of 2024 SIs. That limit is the alternative to treating office-holding as authorship of every later series.
