The by‑election taking place on Thursday in Makerfield, in Greater Manchester, has evolved into one of the most consequential political contests in Britain in recent years, with analysts warning it could shape Prime Minister Keir Starmer’s political future.
At the centre of the race is Manchester Mayor Andy Burnham, who is seeking a return to Westminster. His election is widely viewed as a potential first step towards a future leadership bid, at a time when Labour is facing its most serious internal crisis since coming to power.
The contest follows the resignation of Labour MP Josh Simmons, but has quickly taken on national importance. By‑elections, normally routine mid‑term votes, rarely carry such weight, yet many now describe this one as an informal referendum on both Starmer’s leadership and Labour’s direction.
Polls consistently show Burnham in the lead, though not by a margin that allows complacency. Surveys place him at around 46 per cent, followed closely by Reform UK candidate Robert Kenyon on 41 per cent. The remaining vote is split among smaller parties, highlighting fragmentation on the right and a possible consolidation of centre‑left voters behind Labour.
The election is unfolding against the backdrop of a deepening crisis within the governing party. Labour suffered setbacks in May’s local and regional elections, while Nigel Farage’s Reform UK made significant gains. In the weeks that followed, dozens of Labour MPs voiced discontent with the government’s direction, openly raising the prospect of a leadership challenge.
Tensions escalated further last week with the resignation of Defence Secretary John Healey and his deputy Al Carns. Both cited disagreements over defence spending, warning that planned funding falls short at a time of heightened geopolitical tension, with the war in Ukraine ongoing, instability in the Middle East and continued pressure from NATO for increased defence investment.
Within this context, the Makerfield by‑election is widely seen as more than a local contest. A Burnham victory would likely return him to the House of Commons and position him as a leading contender in any future leadership race.
Conversely, a win for Reform UK would represent a major blow for both the government and Starmer personally, potentially accelerating internal moves against him.
For many in Westminster, this is no ordinary by‑election, but the opening chapter of a potential leadership struggle within Labour. Under party rules, a formal challenge requires the support of at least 20 per cent of Labour MPs, currently 81 signatures. Any leadership candidate must also be a sitting MP with the backing of the same threshold, while the incumbent leader can stand without nominations.
Starmer has already indicated he would contest any leadership race, should one be triggered. That makes Thursday’s vote not just a test of electoral strength, but a pivotal moment that could define the next phase of British politics.
