Andy Burnham, the mayor of Greater Manchester, has emerged as the clear frontrunner to become Britain’s next prime minister, after former health secretary Wes Streeting abandoned his own ambitions and endorsed Burnham in the contest to replace Keir Starmer. The shift, confirmed as the Labour Party prepared to open nominations on July 9, has rapidly narrowed a race that only days ago looked open.
Starmer announced his resignation on June 22, ending a premiership that began with a landslide in 2024 but collapsed under the weight of dismal local-election results and persistent internal revolt. "The question my party is asking now is whether I am best placed to lead us into the next general election," he said, acknowledging that the answer had become no.
Burnham’s path back to national politics ran through the Makerfield by-election on June 18, which he won with about 55 percent of the vote and a majority of more than 9,200 over Reform UK — a seat vacated specifically to give him a route into the Commons. Newly sworn in as an MP, he is now eligible to stand for a leadership he has been linked to for years.
The endorsements are stacking up quickly. Streeting, who had reportedly secured enough nominations to run, said he would instead back Burnham and work to build "an inclusive party," and former deputy prime minister Angela Rayner has also signalled support. Under Labour’s rules, candidates need backing from at least 81 MPs — 20 percent of the party’s 403-strong parliamentary caucus — a threshold that consolidating support behind one figure makes far harder for rivals to clear.
The party has set a compressed timetable: nominations open July 9 and close July 16, with a new leader installed before MPs return from summer recess in September. That schedule reflects an urgent desire to end the drift and present a settled government before the autumn.
The crisis that toppled Starmer was months in the making. In May’s local elections Labour shed 1,496 council seats while the hard-right Reform UK gained 1,453, a near-mirror-image collapse that convinced many MPs the party was sleepwalking toward defeat. Discontent over policy and personnel had already cost Starmer his defence secretary, John Healey, and armed forces minister Al Carns, who resigned on June 11 in a dispute over defence spending.
Burnham’s appeal rests on precisely the terrain Labour has been losing. As a two-term metro mayor he cultivated an identity distinct from the Westminster leadership, championing regional devolution and working-class "red wall" constituencies that have drifted toward Reform. His challenge, should he win, is to convert that outsider brand into governing authority — and to do so as a prime minister who, like his two predecessors, will take office without having won a general election in the job.
