Sir Keir Starmer has been plunged into fresh turmoil following the Green Party's comprehensive win in the Gorton and Denton by-election – with Labour limping home in third place.
Hannah Spencer, a 34-year-old plumber who took the seat with a big win over Reform and Labour, said voters had “rejected hate and embraced hope”.
The prime minister, meanwhile, has vowed to “keep fighting” after insisting that he understands the public is “impatient for change”.
It appears unlikely that Sir Keir will face an immediate challenge for the leadership, with the more likely time expected to be following May's local elections. Angela Rayner said the defeat must be a wake-up call for the party and called for a “braver” approach to politics.
Green leader Zack Polanski said the result showed there were no “no-go areas” for the party.
Writing exclusively in The Independent, he said: “On Monday, Hannah Spencer MP will walk into Parliament as the North’s first Green MP; as the first female plumber to sit in the House of Commons; and as a symbol of what we can do when we put fear aside and back hope instead.
“And that will only be the beginning. In May, there are local elections all across the country, for councillors and mayors – and after this breakthrough, the sky is the limit for our party.”
The victory is the Greens’ first-ever in a parliamentary by-election and comes despite Labour having won Gorton and Denton in 2024 with more than half the vote.
