Labour held Holborn and St Pancras in a byelection that was supposed to test whether the Greens could seriously threaten the governing party's left flank. The answer, for now, is no — but the reasons tell you more about Green self-destruction than Labour vitality. Sagal Abdi-Wali took 12,292 votes to Zack Polanski's 8,928, a margin of 3,364. Turnout was 38.7%, the lowest of any English byelection this parliament and down 15.4 points from 2024. Starmer won the seat with an 11,572 majority last year; the byelection margin is a fraction of that, and the low turnout means Labour's vote total is far below general election levels. This is a hold, not a mandate. The Green campaign arrived pre-damaged. The party's conference voted Sunday to declare Zionism a form of racism and call for Israel's replacement by a single Palestinian state — a motion opposed by four of five Green MPs. The head of Jewish Greens said she may leave the party. Polanski, the party leader, missed the debate, didn't vote on the motion, and drew public criticism from his predecessor Caroline Lucas for a 'lack of leadership.' That sequence — an incendiary policy vote, an absent leader, a former leader rebuking him on television — is not a platform you win byelections from. The Greens' broader polling decline predates the conference. After peaking last summer, buoyed by their February win in Gorton and Denton, Polanski's personal approval ratings and party standing have slid. The conference debacle accelerated a trend already in motion. George Galloway, running from outside the UK, collected 314 votes — enough to be a footnote, not enough to be an alibi. For Andy Burnham, the result provides a floor. His first electoral test as prime minister didn't collapse, and polling suggests he has recovered some of the support Starmer hemorrhaged. But a 38.7% turnout in inner London is not a ringing endorsement — it is the sound of Labour voters staying home and just enough turning up to prevent embarrassment. Reform UK's Zia Yusuf injected a different kind of toxicity, accused by Labour of 'straightforward racism' after suggesting Abdi-Wali — a former child refugee from Somalia and leader of Camden council — was being 'foisted' on voters and questioning her Britishness. The attack didn't move votes in this constituency but signals how Reform intends to contest diverse urban seats. The structural read: the British left's anti-Labour vote remains fragmented. The Greens' eco-populist project depends on disciplined messaging and a credible leader — and this week delivered neither. Labour didn't win this byelection so much as the Greens lost it.
