Zack Polanski, leader of the UK Green Party, has responded to a member-led vote defining Zionism as racism by calling for structural reforms that would concentrate strategic authority in the leader's hands. The move, published in The Guardian on Sunday, reframes a democratic outcome that embarrassed party leadership as evidence that the party's internal processes need top-down correction. The motion passed at the Green Party's annual conference on October 4, calling for Palestinian liberation, the right of return, BDS, and a full arms embargo against Israel. It drew condemnation from Jewish groups, other parties, and most Green Party MPs. Polanski was not present for the vote, citing his focus on the Holborn and St Pancras by-election — a race he subsequently lost to Labour's candidate in the seat vacated by former leader Keir Starmer. The by-election result compounds the political damage. Labour held the seat under Prime Minister Andy Burnham's government, fending off what was expected to be a strong Green challenge from the left. Polanski's absence from the conference vote and his defeat at the ballot box left him answering for both simultaneously. Israel barred him from entering the country after the motion passed. Polanski's proposed reforms are vague on specifics but clear on direction: leaders should have "more responsibility to set the party's strategic direction" while maintaining "wider engagement for members." The tension between these two goals is unresolved. In practice, giving leaders veto or agenda-setting power over conference motions would represent a fundamental shift from the Greens' tradition of grassroots, member-driven policy formation. The political logic is transparent. Minor parties live and die by discipline; a motion that alienates potential coalition partners and dominates media coverage for the wrong reasons is a strategic liability regardless of its merits. But the remedy Polanski proposes — centralizing control to prevent inconvenient democratic outcomes — is the same playbook used by Labour under Blair and Starmer to marginalize left-wing membership. The Greens' selling point has always been that they don't do this. Polanski acknowledged that some members feel "let down" by his absence from the vote but insisted he would stay on as leader. His framing positions the Zionism motion as a process failure rather than a substantive policy position held by the membership, sidestepping the question of whether he agrees or disagrees with the motion's content. The deeper question is whether the Greens can maintain internal coherence as they scale from protest party to electoral contender. Every growing party faces this tension. The answer Polanski is reaching for — more leader control, less membership autonomy — is a well-worn path, but it is not the one the Green Party's base signed up for.
