Keir Starmer resigned as UK Prime Minister on Monday, saying he will stay on as caretaker until the Labour Party selects a new leader. The announcement came without prior warning and immediately triggered a leadership contest that has placed Manchester Mayor Andy Burnham as the front-runner.
The resignation announcement
Starmer made the statement from Downing Street, confirming he would remain in the role only until his successor is chosen. He did not specify a reason for the sudden departure. The timing—just months before the next scheduled general election—has caught both party insiders and the public off guard.
Andy Burnham takes the lead
Within hours of the resignation, betting markets and political observers pointed to Burnham as the early favorite. The Greater Manchester mayor has long been a prominent figure in Labour, known for his vocal advocacy on regional issues and his strong performance in the 2024 mayoral election. No other candidates have officially declared yet, but party insiders expect a field of at least four contenders by the end of the week.
What happens next
The Labour Party's National Executive Committee will meet in the coming days to set a timeline for the leadership vote. Under party rules, Starmer will remain caretaker prime minister until a new leader is elected. The process typically takes about three months, meaning a new prime minister could be in place by late autumn. Until then, Starmer is expected to handle only routine government business.
Burnham has not yet made a public statement about his candidacy. His team is reportedly preparing a campaign focused on economic recovery and public services.
