Recent approval from Labour’s National Executive Committee for Andy Burnham to enter the candidate selection process has reinforced his position as the frontrunner in the Makerfield by-election scheduled for 18 June. Traders have priced in his established local profile as Greater Manchester mayor and the constituency’s Labour heritage, even as Reform UK’s Robert Kenyon benefits from the party’s strong 2024 general-election performance in the seat. Other candidates remain marginal, reflecting limited expectations of breakthroughs by the Conservatives, Liberal Democrats, Greens or independents. The outcome hinges on selection confirmation later this month and campaign dynamics in a constituency where national Labour trends and Reform’s regional support create a competitive but Labour-leaning environment.
