Andy Burnham, the Mayor of Greater Manchester, has been offered a pathway to return to the UK Parliament and potentially challenge Keir Starmer for the Labour leadership. Labour MP Josh Simons announced he would stand down from his Makerfield seat, triggering a by-election that would allow Burnham to contest the seat and re-enter Westminster. Simons stated he was stepping aside specifically to enable Burnham’s return, describing it as Burnham’s "home" . Burnham has confirmed his intention to stand as the Labour candidate in the Makerfield by-election .
The move follows months of speculation about Burnham’s ambitions to return to Parliament, after Starmer previously blocked him from running in the Gorton and Denton by-election earlier in 2026. Burnham’s supporters within the Labour Party had expressed frustration over this decision . If successful in the by-election, Burnham would be positioned to launch a leadership challenge against Starmer, whose premiership is described as increasingly precarious amid internal Labour divisions .
Defence Minister Al Carns, elected in 2024, has also indicated he would launch his own leadership bid if a contest arises. Carns, a junior minister, has criticized Labour’s disconnect from working-class voters, arguing the party has failed to address their economic and emotional insecurities. He questioned Labour’s ability to represent regions like Sheffield, Stoke-on-Trent, and Swansea, emphasizing the need for the party to reconnect with its traditional base .
The Makerfield by-election is expected to be fiercely contested, with Reform UK leader Nigel Farage announcing the party will "throw absolutely everything" at winning the seat, further complicating Labour’s efforts to retain it . Starmer has reportedly indicated he will not block Burnham from standing in the by-election .
