Andy Burnham may run in a by-election after MP Andrew Gwynne stepped down for health reasons, pending Labour party approval.

Andy Burnham, mayor of Greater Manchester, is considering a return to Parliament after MP Andrew Gwynne announced his resignation due to health reasons, triggering a by-election in Gorton and Denton. Burnham’s potential candidacy hinges on approval from Labour’s National Executive Committee, with internal party divisions emerging—some MPs and unions support his bid, calling any block a “democratic outrage,” while allies of Prime Minister Keir Starmer reportedly oppose it, citing concerns over government stability. If selected, Burnham would need to resign his mayoral role, which includes serving as a police and crime commissioner, making it legally incompatible with being an MP. The by-election is expected to be competitive, as Labour’s national support has weakened and Reform UK plans a strong challenge. Burnham has not confirmed his intentions, and the NEC’s stance remains unclear.
