Zack Polanski’s Leadership Tested Ahead of the Holborn & St Pancras Byelection
By Drooid · · How we work
Byelection Stakes and Leadership Claims
The Green Party of England and Wales is fielding its leader, Zack Polanski, in the Holborn & St Pancras parliamentary byelection to fill the seat formerly held by Sir Keir Starmer. The poll opens on October 8. Polanski has asserted that his authority as party leader “doesn’t depend on it whatsoever,” describing the race as “probably 50/50 right now” and “really on a knife edge.”
Recent Rise and Rapid Decline of Green Support
Under Polanski’s year-long leadership the Greens surged to a record 18 % in national polls and won the Gorton and Denton byelection, defeating Matt Goodwin. Since Labour’s recent resurgence, Green support has fallen to roughly 11 %, and internal morale appears strained.
Poll Numbers, Vote History, and Approval Ratings
- In the 2019 Cities of London & Westminster contest Polanski received 728 votes.
- Labour’s incumbent majority in Holborn & St Pancras is 11,572 votes.
- Green polling peaked at 15 % in March, then slipped to around 10 % according to Sir John Curtice.
- Polanski’s net approval rating dropped from -8 % earlier in the year to -27 % last month after controversies involving a post about the Golders Green stabbing investigation.
Official Statements & Party Responses
Polanski frames the byelection as a test of national climate policy rather than his personal leadership. He argues a win would add pressure on the Labour government, while a loss would not trigger a leadership challenge under the party constitution. The Green Party executive rejected his proposal to postpone the annual conference, indicating internal disagreement over resource allocation.
Criticism & Opposition
Senior Greens—including former leader Caroline Lucas, former co-leader Adrian Ramsay, and co-deputy leader Rachel Millward—have distanced themselves from a motion declaring “Zionism is racism,” warning it could be divisive. Some Jewish members have voiced concern about potential disciplinary repercussions, a point Polanski denied.
Verbatim Quotes
- “I’ll be completely honest, it won’t surprise you to know that I want to win the seat,” — Zack Polanski
- “I can guarantee that this motion has absolutely nothing to do with disciplinary action against anyone.” — Zack Polanski
- “I see this election as high-stakes for people in Holborn and St Pancras and high-stakes for the climate crisis,” — Zack Polanski
Conflicting Reports & Gaps
Sources agree Labour holds a sizable majority, but projections differ. The Guardian emphasizes Polanski’s optimism about a “50/50” race, while GB News cites Curtice’s assessment that the Greens are now “four points behind Labour.” No source provides a definitive probability of a Green victory.
What’s Next – Election Day and Potential Leadership Recall
The decisive vote will occur on October 8. Should Polanski lose, party rules allow a leadership recall if 10 % of members sign a petition, and the Green Party Council could trigger a contest with a two-thirds majority. Polanski has ruled out any partnership with Sir Keir Starmer but remains open to cooperating with Andy Burnham on issues such as reforming the far-right.
The outcome will shape both the Greens’ parliamentary prospects and the stability of Polanski’s leadership.
