A Controversial Motion Creates a Political Storm

The controversy began at the Green Party’s annual conference in Brighton in October 2026, when party members voted in favour of a motion declaring Zionism a form of racism. The motion received 1,022 votes in favour and 813 against, making it an official party policy. It described Zionism as an ideology supporting an ethnonationalist Jewish state in historic Palestine and advocated a single democratic Palestinian state across the territory.

The decision immediately attracted criticism from several political figures, Jewish organisations and members of the Green Party itself. Critics argued that the motion risked treating Jewish national identity as inherently racist and could make Jewish members who identify as Zionists feel unwelcome. Others raised concerns that the proposed single-state approach did not adequately address the national rights and security of Israelis.

However, supporters of the motion argued that their position was directed against political nationalism, occupation and the treatment of Palestinians rather than Jewish people as a religious or ethnic community. They maintained that criticism of Zionism and opposition to Israeli government policies should be recognised as legitimate political positions.

This distinction is central to the controversy. Zionism has historically referred to the movement supporting Jewish self-determination and a Jewish national home, but the term encompasses different political traditions and interpretations. Opposition to Zionism is not automatically antisemitic. Equally, criticism of Israel does not justify hostility towards Jewish people or the use of antisemitic stereotypes.

Polanski Faces Questions over His Leadership

One of the most damaging aspects of the controversy for Polanski has been his decision not to participate in the conference vote. Instead, he concentrated on campaigning in the Holborn and St Pancras by-election, which was taking place at the same time.

Polanski subsequently explained that the parliamentary contest was extremely important for his party and required his full attention. Nevertheless, his absence attracted criticism from prominent Green politicians who believed that the party leader should have been present during such a significant policy decision.

Former Green Party leader Caroline Lucas was among those expressing concern about the situation. Other senior figures argued that Polanski had missed an opportunity to demonstrate leadership and protect the party’s reputation.

The controversy became particularly difficult because Polanski had previously expressed reservations about the wording of the motion. Before the conference, he had described the proposal as unhelpful and suggested that amendments were necessary. However, when the motion was passed, his absence left questions about why he had not taken a clearer public position.

His political difficulties were further compounded by the result of the Holborn and St Pancras by-election, where the Green Party finished second behind Labour. Although the Greens increased their vote compared with previous elections, the result represented a missed opportunity for Polanski to enter Parliament.

His Response Creates Further Debate

In the days following the conference, Polanski attempted to clarify his position. On 9 October, he told BBC Breakfast that he would not have voted for the original motion because he considered it imperfect. He indicated that he would have supported an amended version instead.

However, his subsequent television appearances created further controversy. During an interview with Laura Kuenssberg on 18 October, Polanski argued that Zionism, in its practical application, was racist. He also questioned the idea that any state had an inherent right to exist under international law.

These comments attracted considerable attention because they went beyond the wording of the original conference debate. Critics questioned whether his position provided sufficient recognition of Jewish self-determination and Israel’s right to security.

Polanski, who is himself Jewish, rejected accusations that his position was antisemitic. He argued that opposing the policies and ideology associated with the Israeli state was compatible with protecting Jewish communities and opposing discrimination.

He also maintained that the suffering of Palestinians must remain central to political discussions about the conflict. Israel, meanwhile, has repeatedly rejected accusations that its military actions in Gaza constitute genocide.

The disagreement demonstrates how difficult it can be to separate debates about nationalism, statehood, religion and human rights in the context of the Israeli-Palestinian conflict.

Divisions Within the Green Party

Perhaps the greatest challenge for Polanski is the growing disagreement within his own party. The Green Party has traditionally presented itself as a broad political movement focused on environmental protection, social equality, human rights and democratic participation.

However, the controversy has exposed differences between members who strongly support the conference motion and those who believe its wording could damage the party’s relationship with Jewish communities.

Four of the Green Party’s five MPs opposed the motion, demonstrating that disagreement exists even among the party’s elected representatives. Vivien Lichtenstein, chair of the Jewish Greens, also criticised Polanski’s handling of the situation and argued that he should have participated in the conference debate.

Such disagreements create a difficult organisational problem. The Green Party operates through a member-led democratic structure, meaning that conference decisions can establish party policy even when senior politicians disagree with the outcome.

Polanski therefore faces a complicated responsibility: respecting the democratic decisions of party members while ensuring that the organisation remains welcoming to people from different religious and cultural backgrounds.

The controversy also raises questions about whether party leaders should have greater influence over strategic decisions. Following the conference, Polanski suggested that internal democratic procedures might need reform to give party leaders more responsibility for setting the organisation’s overall direction.

Political Consequences and Public Confidence

The controversy has provided an opportunity for political opponents to challenge the Green Party’s credibility. Labour and Conservative politicians have criticised the motion, while Jewish organisations have raised concerns about its potential implications.

The Equality and Human Rights Commission has also sought further information from the Green Party about the policy. This development has increased the importance of explaining how the party intends to apply its position consistently with equality and anti-discrimination obligations.

Another consequence concerns the Green Party’s relationship with Jewish voters. Some Jewish members and supporters have expressed concern about whether they can continue participating comfortably in the organisation. Others believe that the party should maintain a strong position against the Israeli government’s actions while ensuring that antisemitism is challenged wherever it appears.

These concerns should not be treated as identical. Jewish people hold a range of political views about Israel and Zionism, just as Palestinians and other communities hold diverse perspectives about the conflict. No single political position should be assumed to represent an entire religious or ethnic community.

For Polanski, maintaining trust across these different groups will be a significant political challenge. His leadership has benefited from growing membership and enthusiasm among younger voters and supporters of Palestinian rights. However, the party must also demonstrate that its policies can accommodate legitimate disagreement without creating an atmosphere of exclusion.

What Happens Next?

Polanski has indicated that he does not intend to overturn the conference decision immediately. Under the party’s current rules, the policy is expected to remain in place until the next opportunity to amend it in 2028.

He has nevertheless expressed a desire to revise the wording and support a position that recognises equal rights and self-determination for both Israelis and Palestinians.

This creates an important question about the future direction of the Green Party. Can it maintain its strong criticism of Israeli government policies while establishing clear protections against antisemitism? Can it defend Palestinian rights without alienating Jewish members who hold different views about Zionism? And can Polanski unite the party after a conference decision that has exposed such significant internal disagreements?

These are not merely communication problems. They concern the party’s political identity, democratic structures and understanding of equality.

Conclusion

The controversy surrounding Zack Polanski and the Green Party’s “Zionism is racism” motion represents one of the most significant challenges to his leadership since taking office. His absence from the conference vote, the subsequent by-election defeat and disagreements over his public statements have intensified scrutiny of his political judgement and the party’s internal divisions.

Nevertheless, the debate should not be reduced to a simple accusation that criticism of Zionism is automatically antisemitic. The distinction between legitimate political criticism and discrimination against Jewish people must remain clear.

Ultimately, Polanski faces the task of reconciling competing expectations within his party while demonstrating that Palestinian rights, Jewish safety and equal treatment can all be defended consistently. The future of his leadership will be closely connected to how effectively he addresses these disagreements and restores confidence among members, supporters and the wider public. The central challenge is not simply defending one controversial conference decision, but establishing a political movement in which human rights and equality genuinely apply to everyone.
