Zack Polanski has held the Green Party of England and Wales leadership since his September 2025 election, overseeing rapid membership growth to over 230,000 and record local election gains including additional council majorities and the party's first Westminster by-election win. Recent scrutiny over an impermissible donation returned in June 2026 and earlier houseboat council tax questions was resolved without formal sanctions, while one councillor defected in August citing policy disagreements. Polanski's announcement of his intent to contest the Holborn and St Pancras by-election, triggered by Keir Starmer's resignation, positions him for a high-profile test of the party's left-wing "eco-populist" strategy against Labour. With the next scheduled leadership election two years after his victory, trader assessments reflect the absence of organized internal challenges or procedural triggers for removal in the near term.
