Prime Minister Keir Starmer is facing intensified pressure to resign after calls from Labour Members of Parliament and departing ministers, but he has not indicated he plans to step down. Several scenarios are being discussed inside the party, ranging from an early leadership challenge to a longer timeline tied to Greater Manchester Mayor Andy Burnham returning to Parliament. As of Thursday, Starmer remained in Downing Street.
One immediate route would be a leadership contest without Burnham, who is not currently an MP. Under this scenario, a sitting Labour MP would need to assemble the backing of more than 80 colleagues to trigger a challenge, or persuade Starmer to set a timetable for leaving office. Former Health Secretary Wes Streeting was reported to have explored launching a contest but did not secure enough support among MPs.
Other potential challengers, including Angela Rayner and Ed Miliband, have not fully mobilized. Even if a challenge were launched, Starmer could choose to fight it and could still win a vote among Labour members.
Burnham’s path back to Parliament
A second scenario depends on Burnham returning to the House of Commons through a by-election. Officials would need to allow him to stand as a candidate, with the Makerfield constituency cited as a potential seat. If Burnham won the by-election, a leadership contest could follow, and Starmer could again decide to contest it.
The Labour Party uses a single transferable vote system that allows members to rank candidates. In a multi-candidate race, that system could make it possible for Starmer to prevail on second-preference votes even if he did not lead on first preferences.
Slower timelines or Starmer’s survival
A third, slower scenario would delay Burnham’s return until after his mayoral term ends in 2028. That would leave Starmer in office longer but potentially weakened, with party management and public standing under ongoing strain.
A fourth scenario is that Starmer survives the challenge period altogether. Nearly 100 Labour MPs have publicly called for him to resign, and more are said to want him to go privately, but Starmer has not signaled an intention to quit. If no viable challenger emerges or succeeds in a leadership bid, Starmer could remain in power, though that would require rebuilding authority and improving Labour’s position in opinion polls.
Attention is likely to remain on whether a credible challenger can gather sufficient MP support, and on whether Burnham is permitted to pursue a route back to Parliament that could trigger a wider contest.
