Labour’s Andy Burnham, the Mayor of Greater Manchester, has won a by-election in the Makerfield constituency in northwest England, strengthening speculation that he could mount a leadership challenge against Prime Minister Keir Starmer.
Burnham secured a decisive victory over Reform UK candidate Rob Kenyon, winning nearly 55 per cent of the 45,510 votes counted and a margin of more than 9,000 votes. The result positions the 56-year-old, often referred to as the “King of the North”, as a leading figure within Labour and a potential contender for the party leadership.
In his victory speech, Burnham said the result could mark a “turning point” for British politics, arguing that the country needed renewed unity and optimism. He warned against what he described as a drift towards “divided, dark politics” and pledged to restore public trust in Labour.
He also said he would seek to make Makerfield “synonymous with bringing about the change this country needs”, while signalling broader national ambitions beyond his role in Greater Manchester, where he has served as mayor since 2017.
Burnham’s win comes at a politically sensitive moment for Starmer, whose popularity has declined since Labour’s landslide general election victory in 2024. The government has faced criticism over sluggish economic growth, strained public services and rising living costs, alongside internal party tensions and leadership speculation.
Labour has also been losing support to both the Green Party and Reform UK, led by Nigel Farage, which has made gains in post-industrial areas in northern England. A poor showing in recent local elections intensified calls within Labour for a change in leadership.
Starmer congratulated Burnham on social media, saying voters had backed “hope and optimism over division and hate”. However, he has repeatedly insisted he will not step down and said he is prepared to face any leadership challenge.
Under Labour rules, a leadership contest can be triggered if a challenger secures backing from at least one-fifth of Labour MPs in the House of Commons. Burnham’s return to Parliament is expected to increase pressure on Starmer from within the party, with some senior figures suggesting an “orderly transition” may be necessary.
Burnham is expected to take his seat in the House of Commons in the coming days and may soon seek talks with the Prime Minister over the party’s future direction. While some allies suggest he is open to a role in government, Burnham is reportedly focused on broader leadership ambitions rather than a Cabinet post.
The result is likely to intensify debate within Labour over its leadership, direction and strategy as it attempts to regain voter confidence amid rising political competition from both the left and right.
