Andy Burnham, the outgoing mayor of Greater Manchester, has achieved a commanding victory in the Makerfield by-election, securing a parliamentary seat and intensifying speculation regarding a potential challenge to Prime Minister Sir Keir Starmer for the leadership of the Labour Party.
Held on 18 June 2026, the contest saw Mr Burnham elected with 54.8 per cent of the vote, amassing 24,937 ballots and a majority of 9,231 over Robert Kenyon of Reform UK, who received 34.5 per cent. This result represented an increase of approximately 9.6 percentage points in Labour’s vote share compared to the 2024 general election, underscoring Mr Burnham’s enduring local appeal amid broader national difficulties for the party.
In his victory address, Mr Burnham characterised the outcome as a pivotal “change moment” for Britain. He reflected on four decades of policies that he argued had inadequately served communities in the region and across the country. Advocating for a renewed approach, he called for reindustrialisation, reforms to Whitehall, and measures to address inequities in the immigration system—priorities frequently highlighted by voters during the campaign. He emphasised the importance of restoring public hope and affirming that politics can effect meaningful positive change.
The by-election victory grants Mr Burnham a platform in the House of Commons, facilitating his long-expressed ambition to pursue higher office within the Labour Party. Observers note that this development places significant pressure on Sir Keir Starmer, who has faced criticism over the party’s recent performance. The Prime Minister has responded by affirming his commitment to remain in office, stating that he would contest any leadership election and urging party unity to avoid internal division.
Reform UK’s second-place finish marks the third consecutive by-election in which the party has achieved this position, following results in Caerphilly and Gorton and Denton. The contest highlighted ongoing shifts in the political landscape, with Reform capitalising on concerns around immigration and economic policy.
Mr Burnham’s success reflects his established reputation as a prominent figure in northern English politics, often referred to as the “King of the North.” His return to Westminster is expected to prompt further discussions within Labour regarding leadership and strategic direction as the party prepares for future electoral challenges.
