Labour retains Holborn and St Pancras seat in by-election

Labour held the Holborn and St Pancras seat on 8 October 2026, as Camden Council leader Sagal Abdi-Wali beat Green Party leader Zack Polanski. Abdi-Wali won 45% of the vote, with 12,292 votes in total. Polanski came second with 33%. Labour's winning margin was 3,364 votes. The Greens performed much better than in the previous election, gaining 22.4 percentage points more. Labour has held this London constituency without a break since 1983. The by-election was called after former Prime Minister Keir Starmer resigned from the seat. It was also a difficult week for Polanski, because the Green Party conference passed a motion saying Zionism is racism. Polanski said he will stay on as Green Party leader despite losing the vote.
