Andy Burnham has returned to Westminster with a decisive victory in the Makerfield byelection, winning 55% of the vote and defeating Reform UK’s Robert Kenyon. The Manchester mayor described the result as the "most consequential byelection of our lives" and a "turning point", immediately fuelling speculation about a challenge to Prime Minister Keir Starmer's leadership.
Burnham secured 24,927 votes, increasing Labour's vote share by nearly 10 percentage points, while Kenyon trailed on 15,696 votes (35%). Rebecca Shepherd of the hard-right Restore Britain party came a distant third with 3,111 votes (6.84%). Turnout was 58.75%, up from 52.5% at the 2024 general election and the highest for a byelection in seven years.
In his victory speech, Burnham said the people of Makerfield had "voted for change" and for "more power for the north and everywhere forgotten by Westminster". He warned that Labour had a "final chance for change" and "must act upon it", a clear nod to his expected leadership bid. He later told reporters he was heading off for a pint.
Political analysts noted the significance of Burnham uniting the progressive vote, with tactical voting evident: the Liberal Democrats received only 163 votes and the Greens 308. However, polling expert John Curtice cautioned against interpreting the result as a wider Labour surge, attributing Burnham's success to "his appeal to those who wanted to see the back of Keir Starmer".
The scale of the victory has intensified pressure on Starmer, with former transport minister Louise Haigh, a key figure in Burnham's campaign, suggesting the prime minister should agree to an "orderly and managed" handover of power. The result follows a week in which more than 100 backbenchers called for Starmer to go, and there is speculation he could face cabinet resignations.
