Labour's national leadership has issued a directive to every council where the party shares power with the Greens: condemn the Green party's new anti-Zionism policy or the arrangement ends. Bridget Phillipson, Labour chair, framed it as a moral obligation. Andy Burnham called the Green motion "antisemitic" from the dispatch box. The ultimatum covers at least 18 councils across England and Wales, most of them modest district or county coalitions where Greens hold a handful of seats. The Green conference motion in question, passed on 4 October by 1,022 votes to 813, equates Zionism with racism, rejects a two-state solution, and calls for Israel's replacement by a single Palestinian state "with equal rights for all." The 1,022 votes represent 0.4% of total Green party membership. Four of the party's five MPs opposed it. The European Greens expressed dismay. Green leader Zack Polanski abstained to campaign in a byelection he subsequently lost, later saying he would not have voted for the unamended motion. Labour's move is structurally significant for what it reveals about centralised party discipline being projected outward. Labour is not merely distancing itself from the Green policy — it is demanding that individual Green councillors publicly repudiate their own party's democratically adopted position as a condition of continued cooperation. The Greens' decentralised structure means local councillors face no internal penalty for doing so, but the demand itself sets a precedent: national parties dictating the ideological boundaries of local coalition partners. The Green party's response was blunt. A spokesperson accused Labour of conflating criticism of Israel with antisemitism, called the intervention "undemocratic," and pivoted to Labour's own vulnerabilities on arms sales and protest policing. This counter-framing — Labour as hypocritical enforcer — is the predictable move, but it sidesteps the genuine internal crisis the motion has triggered within the Greens themselves. That crisis is real. The chair of Jewish Greens called for Polanski's resignation. Jewish members raised fears of disciplinary action for belonging to Zionist-affiliated organisations, including synagogues. A proposed amendment explicitly protecting members from discipline based on Jewish institutional affiliation was voted down. Salma Yaqoob, a motion backer and former Respect party member, insisted no such discipline would occur — but the defeated amendment tells its own story about what the conference majority was willing to guarantee. Polanski's response has been to float structural reform — giving leaders more control over strategic direction. This is a remarkable concession from a party whose identity is built on grassroots democracy. The motion passed with just over 55% of votes cast at conference, representing a tiny fraction of the membership, yet it is now binding policy that has triggered an existential coalition crisis and may reshape the party's own governance model. The practical consequences are concentrated in local government. Councils like Sheffield, Coventry, Stafford, and Monmouthshire face the loss of coalition stability. In many cases, Greens hold only a few seats but provide the margin that keeps Labour or Lib Dem administrations in power. The ultimatum forces Green councillors into a loyalty test: their national party's conference policy, or their local governing role. Labour is betting that local pragmatism wins — and that the reputational cost to any Green councillor who refuses is higher than the cost of publicly breaking with their own party.
