Sir Keir Starmer has announced his resignation as leader of the Labour Party, bringing his tenure at 10 Downing Street to an end. He said he would remain UK prime minister until a successor is elected and formally takes office.
Although the Labour Party has yet to announce an official timetable, Starmer said in his resignation speech that prospective candidates would have between 9 July and 16 July to secure the nominations required to enter the leadership race.
Under Labour Party rules, candidates must be nominated by at least 81 Labour MPs, along with either 32 of the party’s 634 local constituency branches or three affiliated organisations, including at least two trade unions.
If more than one candidate qualifies, Labour members and affiliated trade union supporters will vote to elect a new leader before Parliament returns from its summer recess on 1 September.
However, there are growing indications that a contested ballot may not be necessary.
Andy Burnham, widely regarded as the frontrunner to succeed Starmer, has returned to Parliament after winning last week’s crucial by-election in Makerfield, north-west England, strengthening his position in the leadership race.
Pressure on Starmer had been building for months amid poor approval ratings for both the Labour government and the prime minister personally.
His position weakened further after documents released earlier this year by the US Department of Justice revived controversy surrounding his appointment of Peter Mandelson as Britain’s ambassador to the United States.
A damaging by-election defeat in February, when Labour lost a previously safe seat to the Green Party after Starmer blocked then Greater Manchester Mayor Andy Burnham from contesting, further undermined his authority and turned the May local and national elections into a referendum on his leadership.
The poor election results prompted Health Secretary Wes Streeting and several junior ministers to resign.
Although Starmer initially vowed to remain in office, his position deteriorated further after Defence Secretary John Healey resigned earlier this month following internal disagreements over defence spending.
Burnham’s decisive victory in the Makerfield by-election, where he fended off a strong challenge from Reform UK, cleared the way for his return to Westminster and a formal leadership bid.
Following Burnham’s victory, Starmer initially insisted he would fight any leadership challenge. However, over the weekend he concluded that Labour MPs wanted a new leader to take the party into the next general election.
Conservative Party leader Kemi Badenoch launched a sharp attack on Starmer following his resignation, describing him as “a terrible prime minister” and urging Labour to appoint a successor without delay.
“The country is not being governed and Labour says there won’t be a prime minister until September,” Badenoch wrote on X.
“Keir Starmer is off on a farewell tour and Andy Burnham wants a summer holiday. Neither is thinking about our national security. We need to cut welfare and fund our military,” she said.
Badenoch also questioned why the country should wait weeks for a new prime minister, particularly as the leadership contest now appears unlikely to be competitive after Wes Streeting, once viewed as Burnham’s main challenger, ruled himself out of the race and endorsed Burnham.
“If you’re not running, what are we waiting for?” Badenoch wrote in response to Streeting’s announcement.
