Recent developments have intensified scrutiny of Zack Polanski’s position as Green Party of England and Wales leader. His second-place finish in the October 8 Holborn and St Pancras by-election, despite a substantial swing toward the Greens, coincided with party conference approval of a motion equating Zionism with racism—a vote Polanski missed while campaigning and later indicated he would have opposed. This prompted public criticism from figures including Jewish Greens chair Vivien Lichtenstein, who called for his resignation, alongside commentary from former leader Caroline Lucas on leadership shortcomings. External fallout included Israel barring Polanski’s entry. Polling showed divided public views on his tenure, yet party rules require a substantial petition or council vote for an early challenge, with the next scheduled leadership election set for summer 2027. These factors shape trader assessments of near-term removal risks.
