Starmer to quit as Labour leader, opening race for No 10

Sir Keir Starmer has announced he is resigning as Labour leader, setting off a succession process that could also determine how quickly he leaves 10 Downing Street.

Starmer has said he will remain UK prime minister until his successor is in place. Labour has not yet confirmed the final timetable for the leadership contest, but Starmer said he would ask the party’s National Executive Committee to open nominations on 9 July and close them on 16 July, when Parliament begins its summer recess.

The resignation follows months of pressure on Starmer’s leadership, according to the BBC’s account, after weak approval ratings for Labour and for Starmer personally, a damaging by-election defeat, poor local and national election results in May and a series of ministerial resignations.

The timetable Starmer wants

Under Labour’s rules, leadership contenders would need nominations from 81 Labour MPs to enter the race. They would also need support from at least 32 of the party’s 634 local branches, or from three affiliated organisations, including two trade unions.

If more than one candidate clears those thresholds, the contest would move to a vote of party members and affiliated trade union supporters. That process would likely run through the summer, alongside hustings and televised debates, with Starmer saying a new leader should be in place by the time Parliament returns on 1 September.

The field may narrow quickly

It remains unclear whether Labour members will ultimately be asked to vote. Former Greater Manchester mayor Andy Burnham, whose election as MP for Makerfield last week cleared the way for a possible leadership bid, has confirmed he will put himself forward.

Former health secretary Wes Streeting, who had been seen as a possible rival, has ruled himself out and backed Burnham. Other potential contenders, including former deputy leader Angela Rayner, have not yet said whether they intend to stand.

If no other Labour MP enters the race, Burnham would become leader without a membership ballot, a scenario that would sharply shorten the transition and speed his path to No 10.

The next decisive moment is now the party timetable: whether Labour’s governing body accepts Starmer’s proposed July nomination window, and whether any candidate besides Burnham can assemble enough parliamentary and party support to force a contest.
