The English and Welsh Green Party just demonstrated the central failure mode of direct democracy at scale: a motivated fraction of 0.4% of total membership passed a policy declaring Zionism a form of racism and calling for Israel's replacement by a Palestinian state. The motion carried by 209 votes. Four of the party's five MPs oppose it. The leader was elsewhere. Zack Polanski's leadership problem is structural, not merely personal. As leader he holds one vote on a 24-member executive committee and no formal veto. But he commands the bully pulpit — the informal power to shape debate, signal boundaries, and rally moderates. He exercised none of it. He offered no definitive opinion on the motion, skipped the vote entirely to campaign in the Holborn and St Pancras byelection, and went near-silent on social media afterward. His critics inside the party are not wrong to call this an abdication. The party tripled in size under Polanski, crossing a threshold where its governance architecture — policy set by whoever shows up to conference or registers online — becomes acutely vulnerable to entryism. Greens for Palestine, the group behind the motion, openly encouraged non-members to sign up specifically to vote it through. This is not a fringe tactic; it is the structural exploit that direct democracy without gatekeeping invites. The party's internal discipline mechanisms are described as 'cumbersome,' which is a polite way of saying they don't work at this scale. The parallels to Corbyn-era Labour are explicit and acknowledged within the party. Some Greens report that activists who left or were expelled from Labour over antisemitism concerns — some via Corbyn's defunct Your Party project — have migrated to the Greens. The institutional antibodies that Labour eventually developed under Starmer do not exist in the Green Party's current structure. Robert Ford, professor of politics at Manchester, delivered the bluntest external verdict: 'This act of self-indulgence by a radical fringe of activists will put a lower ceiling on Green support right at a time when a broader breakthrough became plausible.' The party was polling above 20% after the Gorton and Denton byelection triumph in February. That ceiling is now materially lower, with legal action under equality laws described as apparently likely. The damage extends beyond one policy motion. The vote obliterated media coverage of what was the Greens' biggest and most ambitious conference. Every other policy announcement, every signal of governing seriousness, vanished beneath the controversy. For a party trying to convert protest votes into durable electoral support, this is the worst possible trade — internal purity for external credibility. Polanski faces a leadership election in under a year. His window to act — to challenge the motion, reform governance, or at minimum articulate a position — is closing. The question is whether a leader whose defining characteristic has been absence at the decisive moment will choose to be present for the next one.
