Burnham wins Makerfield by-election, boosting Labour leadership speculation

Andy Burnham turned the Makerfield by-election into more than a routine Labour hold. He won 24,937 votes, or 54.8%, defeating Reform UK’s Robert Kenyon on 15,696 votes and 34.6%, and delivered a majority of 9,241 that sent him back toward Westminster with fresh political momentum.

The result mattered because Burnham did not merely defend Labour’s position in the seat. Sir John Curtice said Burnham retained and increased Labour’s 2024 vote share in Makerfield, a notable contrast with recent by-election swings that have punished the party elsewhere. Curtice described the outcome as a “remarkable personal success” for Burnham, underlining that the victory reflected more than party loyalty.

That distinction is central to the political reading of the contest. Labour has been under pressure from Reform UK in a series of bruising local contests, and Curtice pointed to earlier losses in Runcorn, where Labour’s vote fell by 14 points, and in Gorton & Denton, where it collapsed by 25 points four months ago. Against that backdrop, Burnham’s improvement on Labour’s 2024 performance in Makerfield stood out as a reversal of the recent drift against the party.

The by-election followed the resignation of Labour MP Josh Simons, who stepped aside to allow Burnham a path back into Parliament. That move has now reopened a national question that has shadowed Burnham for years: whether the Greater Manchester mayor is building not just a route to Westminster, but a platform from which to challenge Sir Keir Starmer. Burnham had already framed his candidacy as a vote to “change Labour,” and the scale of his win gives that message new force.

For Labour, the political meaning is twofold. Burnham’s return gives him a parliamentary base at the same moment he has shown he can outperform the party’s recent by-election record. For Starmer, it means a familiar internal rival now has both an electoral mandate and a fresh route back into the national arena.
