Adrian Ramsay, the former Green party leader and current MP for Waveney Valley, has publicly diagnosed what he calls a "crossroads" for the party: a structural vulnerability in its internal democracy that allows small, organised factions to capture policy. The specific trigger is a "Zionism is racism" motion passed at the party's annual conference by what Ramsay says was 0.4% of the membership — a figure he argues is not remotely representative of the broader base. Ramsay's critique is precise and structural rather than purely ideological. He identifies a pattern of entryism — individuals from failed hard-left movements (George Galloway's party, Jeremy Corbyn's Your Party, the SWP orbit) migrating into the Greens and importing factional organising tactics alien to the party's consensus-building culture. He is careful to welcome membership growth broadly while drawing a line at what he calls a "very different culture" of political operation. The institutional mechanics matter more than the personalities. Green party rules currently prevent a policy motion from being reviewed for two years after passage. Conference attendance is small relative to total membership, creating a structural opening for organised minorities. Ramsay wants a ballot or survey of the wider membership and a rule change allowing faster policy review — essentially arguing the party's direct-democracy machinery has become a weapon for the least representative voices. The counter-argument came from Greens Organise, the grassroots group backing current leader Zack Polanski. Their framing is blunt: Ramsay ran for the leadership and lost by 84%. Over 150,000 members have joined under Polanski. Electoral success is unprecedented. The implication is clear — Ramsay is relitigating a settled contest. Ramsay explicitly declined to call for Polanski's resignation or to leave the party himself, but he did say Polanski should have been present for the conference debate and vote rather than campaigning in Holborn and St Pancras. He also rejected the Zionism-is-racism framing directly, calling it contradictory to the 2024 Green manifesto's support for self-determination for both Palestinians and Israelis. The deeper tension is a version of a problem every growing movement faces: how do you scale membership without losing institutional control over what the party actually stands for? The Greens' conference-sovereignty model was designed for a small, ideologically coherent party. At 150,000+ members, it becomes a vulnerability — a system optimised for participation that can be gamed by the most motivated fraction of a percent. Whether this is a genuine institutional crisis or a factional skirmish dressed up as one depends entirely on whether the 0.4% figure holds and whether the leadership moves on rule reform. If the rules don't change, the same dynamics will repeat at the next conference, on whatever issue the organised minority chooses to prioritise.
