The United Kingdom is preparing for a new prime minister after Keir Starmer resigned as Labour leader, triggering a leadership contest that is expected to determine his successor in the coming weeks.
Starmer said he would continue to serve as caretaker prime minister until Labour members elect a new leader. His departure follows months of mounting internal pressure after political setbacks and declining approval ratings.
Labour secured a decisive general election victory in 2024 under Starmer’s leadership, but subsequent losses in local and regional elections across England, Scotland and Wales sharply weakened his position. The fallout intensified calls from within the party for a change of leadership.
In a statement outside 10 Downing Street, Starmer acknowledged that a significant number of Labour MPs no longer believed he should lead the party into the next general election. He said: “The question my party is asking now is whether I am best placed to lead us into the next general election. I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace.”
The resignation comes after reports that more than 100 of Labour’s 403 MPs had urged him to step aside, alongside growing public speculation over his future.
Attention has now turned to Andy Burnham, the Greater Manchester mayor since 2017, who is widely seen as the frontrunner to succeed him. Burnham recently won a decisive by-election in the Makerfield constituency, securing a return to the House of Commons and positioning himself for a leadership challenge. Under Labour rules, the party leader must be a sitting MP.
Burnham, a former cabinet minister and MP in the 2000s, warned in his by-election victory speech that Labour faced a “final chance to change”. If he secures the leadership, he could become prime minister due to Labour’s large parliamentary majority.
He is expected to be sworn in as an MP on Monday. UK media reports suggest he may seek major cabinet changes, including replacing Chancellor Rachel Reeves while retaining Home Secretary Shabana Mahmood, although he has not set out a detailed policy agenda.
Starmer’s resignation follows a turbulent period marked by policy reversals, ministerial resignations and internal disputes. Pressure intensified after Labour’s poor performance in local elections earlier this year, which ultimately contributed to the chain of events leading to his departure.
If the leadership contest confirms a successor, Britain will have had seven prime ministers in just over a decade, underscoring a period of sustained political instability.
