Andy Burnham, the Labour mayor of Greater Manchester since 2017 and re-elected for a term through May 2028, is actively seeking a return to Parliament as the party's candidate in the Makerfield by-election scheduled for June 18, 2026. A successful outcome would disqualify him from holding the mayoral office under UK rules prohibiting dual mandates, prompting his departure from the role. Recent party maneuvering, including an earlier blocked bid for another constituency, has cleared this path amid speculation about his national ambitions. The by-election result and any subsequent confirmation of resignation will determine the timing of any exit before the next scheduled mayoral contest.
