Holborn & St Pancras By-election: Greens vs Labour in a Test for Prime Minister Andy Burnham
By Drooid · · How we work
By-election Overview
The parliamentary seat of Holborn & St Pancras will be contested on October 8. Green Party leader Zack Polanski faces Labour’s Sagal Abdi-Wali, leader of Camden Council. The vacancy arose after former Prime Minister Keir Starmer resigned his MP seat in September 2026.
Political Background
Labour has held the constituency since its creation in 1983, most recently with a 48.9 % vote share in the 2024 general election. The Greens entered the 2024 election with four seats, briefly led national polls in May 2026, and won control of three London boroughs in the May local elections.
Candidate Profiles
- Zack Polanski – 43-year-old Green leader, former London Assembly member.
- Sagal Abdi-Wali – 42-year-old Somali refugee, Camden Council leader since May 2026.
Polling Data & Election Statistics
- YouGov’s latest two-horse poll shows Labour ahead 28 % to 26 %.
- Earlier YouGov tracking placed the Greens at 11 % nationally, down from a 21 % peak in early 2026.
- Starmer won the seat in 2024 with a majority of 11,500 votes; the 2019 majority was nearly 28,000.
- The electorate is young (48 % aged 18-34) and diverse (? 45 % born overseas).
Campaign Issues
1. Housing and utilities – Both candidates pledge public ownership of water and stricter rent controls.
2. Israel-Palestine – The Greens adopted a motion classifying Zionism as racism, drawing condemnation from the Board of Deputies and a ban on Polanski from Israel.
3. Voter outreach – Greens target Muslim voters with leaflets in Bengali and Somali; Labour highlights Abdi-Wali’s refugee background and council record.
Official Statements & Responses
Prime Minister Andy Burnham frames the by-election as a test of his government’s ability to win back left-wing voters. Green leadership calls the contest “truly historic” and says a win would push Labour toward stronger rent-control and water-nationalisation policies.
Criticism & Opposition
The Zionism motion sparked criticism from British Jewish groups. All five Green MPs publicly distanced themselves from the vote, which Polanski missed.
On-the-Ground Reports
Local residents describe a mixed response.
Conflicting Reports & Gaps
Polling figures vary: the Guardian cites a brief 21 % Green peak, while Independent-linked reporting places the current share at 11 %. YouGov’s two-horse poll (28 % vs 26 %) differs from the Independent’s claim that the Greens are “11 % behind Labour.” No definitive post-poll analysis is available, leaving the exact scale of Green momentum uncertain.
What’s Next
The October 8 by-election will be the first major electoral test for Prime Minister Burnham’s administration. Observers expect the result to indicate whether Labour can reclaim left-wing voters in inner-London constituencies and to gauge the Greens’ capacity to translate local successes into a Westminster foothold.
