TL;DR
Andy Burnham is the UK's new prime minister. He formally took office on Monday, July 20, 2026, after King Charles III asked him to form a government at Buckingham Palace — becoming Britain's seventh prime minister in a decade (CNN; ABC News; Deadline).
Keir Starmer resigned first: he informed the King of his resignation earlier the same day, then Burnham travelled to the Palace to be appointed.
In his first address outside 10 Downing Street, Burnham pledged to "regain our stability," called his arrival a "circuit-breaker," and promised a new political and economic model built on a 10-year plan.
How he got the job: Burnham won the Labour leadership unopposed on July 17, nominated by 379 of 403 Labour MPs (94%) — the largest share in a modern Labour contest. With one qualifier, there was no members' ballot.
Next to watch: Burnham's first cabinet, expected to be announced later on July 20, with big changes tipped at the Treasury, Foreign Office and Home Office. Lisa Nandy is reported to be leaving the Foreign Office to run a new "super ministry" for the north of England.

It's done (July 20, 2026): Andy Burnham is prime minister. Keir Starmer went to Buckingham Palace to formally tender his resignation to King Charles III, and Burnham followed to be asked to form a government (CNN; ABC News). He was then seen entering 10 Downing Street as PM. Burnham is the United Kingdom's seventh prime minister in ten years.
*
His first words as PM: speaking outside Number 10, Burnham said Britain must show "that we can regain our stability," framing his appointment as a "circuit-breaker" for the country and pledging a new political and economic model anchored in a 10-year plan (CNN).
*
A record mandate behind him: Burnham won the Labour leadership on July 17 running unopposed, nominated by 379 of the 403 eligible Labour MPs — 94% of the parliamentary party, the largest share in a modern Labour leadership contest, exceeding the 88% Gordon Brown received when he succeeded Tony Blair unopposed in 2007. Because Labour is in government, the party leader takes Downing Street, so no separate election was needed to make him PM.
*
How we got here: Keir Starmer announced his resignation as Labour leader on June 22, 2026, after months of pressure over policy U-turns and a loss of confidence among Labour MPs. Every other name seriously floated — Wes Streeting, Darren Jones, former defence minister Al Carns — ruled themselves out, several endorsing Burnham. When nominations closed on July 16, he was the only candidate to qualify, so under Labour's rules the August members' ballot was cancelled and he was elected unopposed.
*
What to watch next: Burnham's first cabinet, expected later on July 20. Reports point to changes in the biggest jobs — Treasury, Foreign Office and Home Office — with Lisa Nandy tipped to leave the Foreign Office to head a new "super ministry" focused on the north of England. The other open question is whether Burnham calls an early general election; he is under no obligation to, as Labour's term runs to 2029.
