**Zack Polanski remains the entrenched leader of the Green Party of England and Wales following his September 2025 landslide election with 85% of the vote.** Under his “eco-populist” direction the party has tripled membership, secured its first Westminster by-election win in Gorton and Denton, and posted record local gains, though recent polling has eased and internal motions have flagged risks of stagnation amid a Labour recovery under new Prime Minister Andy Burnham. Polanski has confirmed he will contest the October 2026 Holborn and St Pancras by-election triggered by Keir Starmer’s resignation and has stated he intends to remain leader regardless of the result. Leadership elections occur every two years, with the next scheduled for 2027, and no formal challenges or resignation signals have emerged. Trader-implied probabilities for removal by late 2026 therefore reflect the absence of imminent institutional or electoral pressure that would force a change.
