Burnham cleared for Makerfield by-election, opening path to Labour leadership

Labour has cleared the way for Andy Burnham to seek a comeback in Parliament, a move that gives the Greater Manchester mayor his first plausible route to a leadership challenge and forces a new debate inside Labour about Keir Starmer’s grip on power.

The party’s National Executive Committee agreed to let Burnham seek selection for the Makerfield by-election after Labour MP Josh Simons said he would stand aside to create the vacancy. Burnham is not an MP, so he must win the seat before he can even enter the frame for Downing Street. That distinction matters: the opening is real, but it is not yet a threat to Starmer.

Any challenge to an incumbent Labour leader still requires nominations from 20% of Labour MPs. With 403 Labour MPs, that means 81 MPs would have to back a rival before a contest could begin. Under the party’s rules, Starmer would automatically be on the ballot if the threshold were reached. In other words, Burnham now has a route back to Westminster, but not a clear path to the leadership.

The timing has sharpened the stakes. Labour has been battered by heavy losses in the May 2026 local elections, and senior figures have begun sounding like a party in open argument about its future. Wes Streeting resigned as health secretary on May 14, 2026, while Angela Rayner has said a probe into her tax affairs had concluded and that she had paid £40,000 in unpaid stamp duty. Streeting has not launched a formal challenge, but has signalled that he wants a broad contest with the “best possible field of candidates.”

Burnham had already been blocked by Labour’s NEC in January 2026 from standing in the Gorton and Denton by-election, which the Green Party later won. Makerfield, near Wigan west of Manchester, now offers him a second chance, and Reform UK is expected to target the seat aggressively. That alone makes the by-election more than a local contest: it is a test of whether Labour can hold working-class ground in the north while keeping its internal succession battle under control.

Starmer allies have insisted the prime minister is focused on holding the party together and is not trying to block Burnham’s candidacy. That is the central question now. Burnham’s route to Westminster is open, but the difference between a genuine succession threat and Westminster overreaction still depends on whether Labour MPs decide that Starmer is vulnerable enough to challenge at all.
