Green Party Leader Seeks Structural Overhaul After Zionism Vote

Green Party leader Zack Polanski has signaled a major overhaul of the party’s grassroots democratic structures, calling for greater leadership control over strategic direction following a divisive vote that equated Zionism with racism, The Guardian reported. Writing in October 2026, Polanski defended his absence from the conference vote due to a parliamentary byelection campaign and admitted that colleagues may feel let down by his lack of intervention.

Green Party Conference Passes Divisive Zionism Motion

The controversy intensified during the party’s autumn conference when 1,022 members voted in favor of a motion declaring Zionism a form of racism and endorsing a single Palestinian state across historic Palestine, according to BBC reporting. The policy passed by 1,022 votes to 813 among attendees, representing roughly 0.4% of the party’s total membership of 230,000. Four of the party’s five MPs opposed the measure, and the European Green party criticized the decision for contradicting its support for a two-state solution.

Westminster leader Ellie Chowns stated that the vote demonstrated an urgent need to modernize policymaking structures to prevent the party from becoming vulnerable to extremists, BBC reporting showed. Former party leader Caroline Lucas also noted that the decades-old constitution required modernization to ensure the party remains welcoming to Jewish people. Meanwhile, organizations including the Board of Deputies of British Jews and the Jewish Leadership Council condemned the motion as institutional failure, arguing that Zionism represents anti-racism and a refuge for persecuted Jews.

Zack Polanski Faces Leadership Scrutiny After By-election Defeat

Polanski faced intense scrutiny after leaving the conference early to contest the Holborn and St Pancras byelection triggered by Keir Starmer’s resignation. Labour candidate Sagal Abdi-Wali won the seat with 45% of the vote, while Polanski finished second with 33%, though the Green vote share rose by 22 percentage points compared to the 2024 general election, BBC reporting noted. Polanski confirmed to BBC Breakfast that he would stay on as leader despite his defeat.

Writing in The Guardian, Polanski explained that his priority was fighting a consequential parliamentary race to drive change through electoral success, though he acknowledged that some members felt let down by his silence on the conference floor. Polanski, who is Jewish and grew up in a Zionist household, stated that while the motion’s substance aligned with his views on Palestinian displacement, political parties should not dictate individual beliefs or attempt to define complex national identities.

Internal Party Structures Facing Pressure From Rapid Membership Growth

Under current Green Party rules, policy is decided directly by members at conference rather than by its leadership, a system that senior figures argue gives disproportionate influence to small, highly motivated activist factions. Polanski argued that rapid membership growth requires structural evolution to grant leaders more responsibility over strategic direction while keeping processes accessible.

Commentators and Jewish community leaders expressed deep concern over the long-term political impact of the vote. Writing for The Jerusalem Post, Rabbi Dr. Jonathan Lieberman argued that the adoption of the motion shifted the Overton window in British politics by making an antisemitic proposition respectable as official party policy. Nation.Cymru contributor Martin Shipton argued that Polanski’s primary mistake was failing to back the motion unequivocally during the conference.

Uncertain Future for Party Policy Reform and Leadership Control

It remains unclear how the Green Party will implement Polanski’s proposed structural reforms or whether upcoming conferences will revisit the contested Zionism policy. While leadership has committed to modernizing internal decision-making processes, the exact mechanism for balancing member-led democracy with executive strategic control has not yet been detailed by party officials.
