Andy Burnham Secures Key Endorsement, Poised to Lead UK Labour Party

Andy Burnham, the man widely expected to replace Keir Starmer as U.K. prime minister, has won the endorsement of a key Labour leadership rival — paving the way for him to lead the country within weeks.

Starmer announced his departure as British prime minister Monday, bowing to pressure after Labour colleague Burnham resoundingly won a by-election that would let him challenge for the top job. In a tearful statement outside No.10 Downing Street, Starmer said he had informed King Charles III of his decision to quit — and set out plans for a Labour leadership contest.

In a significant boost, Burnham has already been endorsed by Wes Streeting, the former cabinet minister who had been expected to be his main challenger for the job.

“Having spoken at length with Andy in recent days, I’m convinced that there is a place for those ideas under his leadership; that he is committed to building an inclusive party that draws on the best of our political traditions; and that he can win the fight of our lives against the forces of nationalism,” he said.

“We could spend the summer exaggerating small differences, or we can roll up our sleeves and help him to deliver the change our Party and our country needs. That is the choice that I am making and I hope that everyone else will back Andy, too”

It comes after Burnham decisively beat the right-wing Reform UK in the Makerfield by-election, making him eligible to challenge Starmer for the leadership of the governing party. The scale of Burnham’s win has helped tip more Labour MPs into his camp.

Starmer said Monday he had asked Labour’s ruling National Executive Committee to launch a leadership contest, with nominations open until July 9 and the race over by the summer parliamentary recess. The aim is to have a new Labour leader in place by September — and Starmer said he will “remain in place until the contest is complete” and “ensure an orderly handover of power.”

But that timeline now looks all-but-certain to be compressed with Streeting backing Burnham.

Since coming to office with a commanding House of Commons majority in 2024, Starmer’s Labour government has repeatedly struggled to gain momentum. It suffered huge losses to Nigel Farage’s right-wing Reform UK in local elections, has been hit my multiple scandals, and Starmer has U-turned on a series of key policies in the face of pressure from his own ranks.
