Andy Burnham, the Mayor of Greater Manchester, has been positioned as a leading challenger to UK Prime Minister Keir Starmer, with polls and bookmakers favoring him as a potential successor. The path for Burnham to challenge Starmer became clearer after Labour MP Josh Simons announced his resignation from the House of Commons, triggering a by-election in the Makerfield constituency. Simons explicitly stated he was stepping aside to allow Burnham, who hails from the region, to return to Parliament—a prerequisite for any leadership bid .
Burnham has confirmed his intention to stand as the Labour candidate in the Makerfield by-election, which would enable him to re-enter Parliament and subsequently launch a leadership campaign against Starmer. His potential candidacy has intensified speculation about Starmer’s political future, with some analysts describing the Prime Minister’s position as increasingly precarious .
The by-election has also drawn attention from other political figures, including Defence Minister Al Carns, who has indicated he would launch his own leadership bid if a contest arises. Carns, a junior minister first elected in 2024, has criticized Labour’s disconnect from working-class voters, arguing the party must address both economic and emotional insecurity to regain support . Meanwhile, Nigel Farage of Reform UK has stated his party will aggressively campaign in the Makerfield by-election, signaling a competitive race .
Starmer’s government has not indicated any plans to block Burnham’s candidacy, allowing the process to proceed without direct interference . The outcome of the by-election will determine whether Burnham can formally challenge Starmer for the Labour leadership.
