Keir Starmer Faces Leadership Challenge After Andy Burnham Wins Makerfield By-Election

Speculation over Starmer's future intensified over the weekend after Burnham's decisive victory in the Makerfield by-election

British Prime Minister Keir Starmer is facing mounting pressure over his future after Labour rival Andy Burnham secured a parliamentary seat, paving the way for a potential leadership challenge. Speculation over Starmer's future intensified over the weekend after Burnham's decisive victory in the Makerfield by-election, with several media reports suggesting the prime minister is considering his options amid growing discontent within the ruling Labour Party. However, senior minister Peter Kyle said there was no confirmation that Starmer was preparing to resign. "I have nothing to believe that they are true. I am seeing a lot of speculation out there," Kyle told Sky News. At the same time, Kyle acknowledged that Starmer was reflecting on the situation confronting him. "Today, as in every other day I've ever known Keir, he is out there working hard. At the same time, he is also trying to create the space where he can think and reflect on the political realities and challenges - and the opportunities - that are before us," he said.

Burnham's return to Parliament raises stakes

Burnham, the mayor of Greater Manchester since 2017, won the Makerfield seat in north-west England on Thursday with nearly 55 per cent of the vote. The victory allows him to return to the House of Commons and formally contest the Labour leadership if he chooses. In his victory speech, Burnham signalled his ambitions. "Everyone knows that politics isn't working. Everyone can feel that the country isn't where it should be. Tonight could, just could, be the turning point," he said, according to AP. As per news agency AFP, Burnham warned Labour had a "final chance to change" and has made clear he intends to seek the party leadership. Under Labour rules, leadership contenders must be Members of Parliament and secure the backing of at least 81 Labour MPs to launch a formal challenge, Reuters reported.

Starmer vows to fight

Despite the speculation, Starmer has insisted he will not step aside voluntarily. "I will run, I will stand," if there is a Labour leadership contest, Starmer said on Friday. "I've said repeatedly I'm not going to walk away from that." A government source cited by Reuters also said that the prime minister remained focused on governing despite reports about his future. Starmer spent the weekend at Chequers, the prime minister's country residence, with his family. On Sunday, he posted a Father's Day message on X but gave no public indication about his plans.

Why pressure is growing

Starmer's position has weakened following Labour's poor performance in local elections in May and declining approval ratings. The prime minister, who led Labour to a landslide victory in the July 2024 general election, has struggled to deliver promised economic growth, ease cost-of-living pressures and improve public services. Labour is also facing pressure on both flanks, losing some progressive voters to the Green Party while seeing support shift towards Nigel Farage's Reform UK, which currently leads several national opinion polls. Starmer's tenure has been marked by policy U-turns, ministerial resignations and controversies, including criticism over the appointment of Peter Mandelson as Britain's ambassador to the United States.

Potential successors emerge

If Starmer steps down, Burnham is widely viewed as a leading contender to replace him. However, he may not have the field to himself. Former health secretary Wes Streeting is also considering a leadership bid. Former minister Jess Phillips told the BBC that "it feels like we've come to the end of the road" for Starmer and that any departure should be handled "as dignified as possible". A departure by Starmer would make him the sixth British prime minister to leave office in the past decade and the seventh in ten years if a successor takes over this year. Burnham is due to be sworn in as an MP on Monday, a development many Labour figures view as the beginning of a decisive week for the party's leadership.
