The former mayor of Greater Manchester is unopposed in the race to replace Sir Keir Starmer.

Andy Burnham is on course to become Labour's new leader, with no other candidate running against him as nominations in the contest open. Labour MPs can now formally endorse contenders to replace Sir Keir Starmer, with an initial total to be published by the party at around 19.00 BST on Thursday. Without other candidates joining the former Greater Manchester mayor in the race, Burnham will be declared leader at a party event at the end of next week. He would then become prime minister on 20 July, just weeks after returning to Parliament after a decade's absence in a by-election in Makerfield. Former defence minister Al Carns, who had suggested he could throw his hat into the ring, ruled himself out on Wednesday evening. The move cleared the path for Burnham to run unopposed, with a series of possible rivals including Wes Streeting already having thrown their weight behind him. Labour's rulebook requires candidates to be nominated by 81 Labour MPs, as well as either 32 of Labour's 634 local branches, or three of the 31 socialist societies and trade unions affiliated to the party, including at least two unions. Candidates have until Wednesday next week to gather the nominations from Labour MPs required to take part.
