U.K. Prime Minister Keir Starmer announced Monday that he will stand down as Labour leader and prime minister, ending months of political turmoil and opening a contest to replace him.

The announcement follows mounting pressure on the prime minister after Labour suffered heavy losses in local elections in May and faced an increasingly vocal rebellion from his own lawmakers over his leadership and policy agenda.

The move comes less than two years after Starmer led Labour to one of its largest parliamentary majorities in the 2024 general election.

Starmer’s Announcement Outside Downing Street

In a statement outside 10 Downing Street shortly after 9:30 a.m. in London, Starmer said he would remain in his post until any leadership contest is completed — a move he said would help ensure an orderly handover of power.

Labour’s former Greater Manchester mayor Andy Burnham won a decisive victory in a special election on June 18, potentially setting up a challenge for the party’s leadership and, by extension, the UK’s premiership.

In a short speech, a visibly emotional Starmer said that entering 10 Downing Street had been the “proudest moment of my life,” adding that under his tenure, Britain’s reputation in the world had been restored, with investment secured and improvements in workers’ rights delivered.

However, Starmer conceded that Labour colleagues had been asking whether he was best placed to lead the party into the next general election.
