UK Prime Minister Keir Starmer has triggered a growing internal backlash within the Labour Party after blocking Greater Manchester Mayor Andy Burnham from standing in a parliamentary by-election — a move critics describe as “brutal” and politically risky.
Starmer used a nine-member committee of Labour’s ruling National Executive Committee (NEC) to prevent Burnham from running in the Gorton and Denton by-election, officially citing the additional costs of holding a mayoral election should Burnham leave his current post.
However, Labour MPs argue the decision was designed to neutralize a popular internal rival, with Burnham widely viewed as a potential challenger to Starmer’s leadership amid slumping poll numbers.
Internal Revolt Builds Inside Labour
According to multiple Labour MPs, a letter demanding a full 39-member NEC review of the decision is already circulating, with more than 50 MPs reportedly backing it, including senior figures. While signatories privately admit the effort may fail, many see it as a symbolic stand against what they view as heavy-handed leadership from No.10.
One MP warned the decision “hastens Starmer’s demise,” while others argue the move could strengthen alternative leadership contenders, notably Health Secretary Wes Streeting, who is increasingly mentioned as a future prime ministerial candidate.
Even MPs who did not support Burnham’s return to Westminster have expressed anger over the manner in which the decision was imposed, deepening factional tensions within the party.
High Stakes Ahead of Local Elections
The controversy comes at a sensitive moment, with local and devolved elections scheduled for May 7 across England, Scotland, and Wales. A potential Labour defeat in Wales, where the party has governed since 1999, would be particularly damaging.
Meanwhile, the Gorton and Denton seat — which Labour previously won by over 13,000 votes — could face strong challenges from Reform UK and the Greens, raising fears of an embarrassing loss that would reignite criticism of Starmer’s decision to block Burnham.
Starmer Defends the Decision
Responding publicly, Starmer insisted that Burnham is “doing a great job” as mayor, arguing that an unnecessary mayoral election would divert resources from elections Labour “must fight and win.”
Despite his strong parliamentary majority from the 2024 general election, the episode has intensified debate over Starmer’s leadership style and whether his efforts to consolidate power may ultimately undermine party unity.
