Overview
- Andy Burnham won the Makerfield by-election with 54 percent of the vote to Reform UK’s 35 percent and Restore Britain’s 7 percent in a contest held on Thursday, with turnout around 58.7 percent and 45,510 votes cast.
- By winning the seat Burnham is now an MP and meets Labour’s rule that a leader must sit in Parliament, creating a credible route for him to stand in a leadership contest if he can secure enough backers.
- Keir Starmer publicly congratulated Burnham and said he would offer him a government role and would recontest any leadership ballot, but party rules require roughly 20 percent of Labour MPs—about 81 MPs—to nominate a challenger before a contest can be triggered.
- Burnham campaigned as a popular 'soft left' mayor focused on shifting power and resources to northern England, a pitch that helped him win back voters from smaller progressive parties rather than peel directly from Reform UK.
- The result intensifies an internal Labour debate over leadership after recent scandal-driven resignations and poor local election results, and the next phase depends on how many MPs and members back a formal challenge and whether the party can manage the transition without deepening instability.
