Labour retained the Holborn and St Pancras seat on 8 October 2026 with Sagal Abdi-Wali securing 45.1% of the vote against Green leader Zack Polanski’s 32.8%, producing a 12.3-point margin that aligns with the market’s dominant 10-15% outcome. Traders priced this heavily after the former prime minister’s resignation triggered the contest, reflecting Labour’s entrenched local base, Abdi-Wali’s profile as Camden council leader, and historically reliable support in the constituency. The Green challenge, while boosted by recent local gains, faced headwinds from internal party divisions following a controversial conference motion, limiting further erosion of the Labour vote. Lower turnout at 38.8% also favoured the incumbent party. Only an unexpected late swing or major counting irregularity would have altered the margin materially.
