Labour Issues Urgent Ultimatum to Greens as Zack Polanski Backs Controversial Anti-Zionist Policy
Britain’s political tensions have intensified after Labour threatened to end its local power-sharing arrangements with the Green Party following a controversial decision on Zionism. The dispute has placed Green Party leader Zack Polanski under renewed pressure and raised difficult questions about antisemitism, Palestinian rights and the future of cooperation between Britain’s centre-left parties.
The controversy erupted after Green Party members voted at their annual conference to adopt a motion defining Zionism as a form of racism. The decision triggered criticism from Labour politicians, Jewish community organisations and several prominent figures within the Green Party itself.
Labour has now demanded that Green councillors involved in local governing arrangements formally reject the controversial motion within a week or face the possibility of their coalitions being dissolved. The ultimatum threatens to disrupt political cooperation in councils where Labour and the Greens currently share power.
The confrontation represents a significant escalation in an already heated debate. It also presents Polanski with a difficult challenge: how can he defend his party’s position on Palestinian rights while addressing concerns from Jewish communities and maintaining relationships with political allies?
Labour Draws a Line Over the Green Party’s Policy
Labour’s response reflects growing frustration within the party over the Greens’ decision to adopt the motion.
Senior Labour figures have argued that defining Zionism as racism crosses a fundamental political and moral boundary. They contend that Zionism, broadly understood as support for Jewish self-determination and the existence of a Jewish state, cannot simply be equated with racism without raising serious concerns about the treatment of Jewish people.
The issue has become particularly sensitive because many Jewish people regard Zionism as an important part of their identity, although Jewish views on Zionism and the policies of the Israeli government are diverse.
Labour’s ultimatum seeks to turn its criticism into a concrete political demand. Rather than relying solely on public statements of disagreement, the party wants Green councillors involved in joint administrations to distance themselves formally from the motion.
If they fail to do so within the specified period, Labour has threatened to terminate the existing arrangements.
Such a move could have practical consequences for local government. Coalition agreements often determine how councils allocate responsibilities, approve budgets and deliver services. Ending those agreements could force political groups to renegotiate their arrangements or attempt to govern without their current partners.
The dispute therefore extends beyond an argument about political language. It could affect the functioning of councils and the relationships between parties that share some policy objectives but disagree sharply on the Middle East.
What Did the Green Party Actually Vote For?
The controversy centres on a motion adopted at the Green Party conference in Brighton in October 2026.
Members voted 1,022 to 813 in favour of defining Zionism as a form of racism and supporting the establishment of a single democratic Palestinian state across historic Palestine. The motion also reaffirmed the party’s opposition to Israeli government policies, including its treatment of Palestinians. <Cite refs={[“turn606976search2″,”turn606976search3”]}/>
Supporters argue that Zionism should be examined in the context of Palestinian displacement, unequal rights and the continuing Israeli-Palestinian conflict. They contend that opposition to Zionism can be a political position directed at a system of national identity and state power rather than hostility towards Jewish people as a religious or ethnic group.
Critics argue that the motion risks denying Jewish people the same right to national self-determination that other peoples claim. They also warn that treating Zionism as inherently racist can stigmatise Jewish people who identify with the movement or regard Israel’s existence as essential to Jewish security.
The distinction between criticism of Israel and antisemitism is central to the disagreement.
Criticism of Israeli government policy, opposition to military action and advocacy for Palestinian rights are not inherently antisemitic. However, language or political demands can raise legitimate concerns when they collectively blame Jewish people, discriminate against them because of their identity or deny them rights afforded to others.
The Green Party’s motion has become controversial because critics believe its wording crosses that boundary. Supporters reject the accusation that their position is inherently antisemitic.
Understanding the dispute requires examining both the wording of the motion and its possible implications for Jewish members and communities.
Zack Polanski Faces Pressure From Both Sides
Polanski has found himself at the centre of the controversy, even though he did not participate in the conference vote.
The Green leader had left the conference to campaign in the Holborn and St Pancras by-election. He subsequently said that he would have voted against the motion while maintaining his support for Palestinian rights and the principle of equal rights for Israelis and Palestinians. <Cite refs={[“turn606976search5″,”turn606976search2”]}/>
His position has not ended the criticism.
Some Jewish Greens and other party members have questioned whether the leadership responded strongly enough to concerns about the motion. Vivien Lichtenstein, chair of the Jewish Greens, called on Polanski to resign, arguing that his absence from the vote and the resulting controversy had damaged confidence in his leadership. Others within the party have defended him and disputed the suggestion that he should step down. <Cite refs={[“turn606976search5”]}/>
Polanski has insisted that antisemitism and criticism of the Israeli state must remain distinct. He has also said that no one should be excluded from the Green Party because of their religious background, faith or communal affiliations.
These statements reflect an attempt to reassure Jewish members while preserving the party’s commitment to Palestinian rights.
However, the political difficulty remains: a leader’s personal explanation does not automatically resolve concerns about an official party policy adopted by members.
Polanski must now contend with questions about how the motion will be interpreted, whether safeguards for Jewish members are sufficient and how the party will respond to those who believe the policy threatens their ability to participate equally.
Why Jewish Community Organisations Are Concerned
Several Jewish organisations have strongly criticised the Green Party’s decision.
Their concerns focus on the possibility that Jewish people who support Israel’s continued existence, or who belong to Zionist synagogues and organisations, could feel unwelcome or face pressure within the party.
The Board of Deputies of British Jews described the motion as an attack on the Jewish community. Other Jewish representatives argued that equating Zionism with racism could stigmatise a significant part of Jewish religious and political life. <Cite refs={[“turn606976search6″,”turn606976search3”]}/>
These objections have particular significance in the context of wider concerns about antisemitism in Britain.
Jewish communities have faced antisemitic incidents and threats, especially during periods of heightened tension surrounding events in Israel and Gaza. Community organisations have therefore called on political parties to distinguish clearly between legitimate criticism of the Israeli government and rhetoric that could contribute to hostility towards Jewish people.
At the same time, Jewish opinion is not uniform. Some Jewish individuals and organisations identify strongly with Zionism, while others oppose Zionism or hold different views about the future political arrangements between Israelis and Palestinians.
That diversity makes it especially important to avoid treating Jewish people as a single political group.
The central concern raised by critics of the Green motion is whether the party’s new position can coexist with a genuine commitment to equal participation for Jewish members who hold different views.
Labour’s Wider Political Strategy
The confrontation also has implications for Labour’s relationships with other progressive parties.
Labour and the Greens compete for support among voters who prioritise public services, environmental protection, social equality and stronger action on climate change. At the same time, they have different political traditions and may disagree on foreign policy, economic questions and the appropriate boundaries of political rhetoric.
Cooperation in local government can allow parties to work together where they share practical objectives. However, controversial national policies can undermine those arrangements when one party believes that its partner has adopted an unacceptable position.
By issuing an ultimatum, Labour is attempting to establish that participation in a joint administration carries responsibilities beyond agreeing on budgets and local services.
The party’s position is that its representatives should not share governing arrangements with councillors who fail to distance themselves from a policy it regards as antisemitic.
The approach could strengthen Labour’s message to Jewish communities that it takes antisemitism seriously. However, it could also create difficulties in councils where cooperation between Labour and Green councillors has been necessary to maintain a governing majority.
If agreements are terminated, both parties may have to reconsider how they work together on housing, transport, local investment and other responsibilities.
The immediate outcome will depend on how Green councillors respond to the demand and whether negotiations can produce a compromise.
Could the Dispute Have Legal Consequences?
The controversy has also attracted attention from the Equality and Human Rights Commission, Britain’s equality watchdog.
Labour MPs have raised concerns about whether the motion and the rejection of proposed protections for Jewish members could create questions under equality law.
The commission has indicated that it will consider complaints carefully, but that does not mean it has automatically determined that the Green Party has broken the law or launched a formal investigation. <Cite refs={[“turn606976search2”]}/>
Any legal assessment would require examination of the party’s policies, their implementation and whether specific conduct amounts to unlawful discrimination.
Political parties are entitled to debate controversial questions about Israel, Palestine and national self-determination. However, they must also comply with applicable equality legislation and their legal responsibilities towards members.
The distinction between political disagreement and unlawful discrimination is important. A controversial policy does not automatically establish a legal violation, but the practical treatment of people affected by that policy may be relevant to an assessment.
For the Greens, the challenge is to demonstrate that their commitment to opposing racism applies consistently to Jewish members, Palestinians and people from all other backgrounds.
The Wider Debate Over Israel and Palestine
The dispute reflects a much broader disagreement about the future of Israel and Palestine.
Supporters of a two-state solution generally advocate the establishment of an independent Palestinian state alongside Israel. They argue that this offers a framework for national self-determination for both peoples.
The Green Party motion instead supports a single democratic Palestinian state across historic Palestine. Supporters believe that a single state could provide equal rights regardless of religious or ethnic background.
Critics question how such a state would guarantee Jewish national self-determination and security, particularly given the history of conflict and the continuing absence of agreement between the parties.
Both proposals raise difficult questions about borders, citizenship, security, refugees, political representation and the protection of minorities.
The debate cannot be reduced to a simple choice between supporting Palestinians and supporting Jewish people. Advocacy for Palestinian freedom and opposition to antisemitism can coexist, just as concern for Israeli security does not require endorsing every decision made by the Israeli government.
The challenge for political leaders is to express their positions clearly without undermining the rights or dignity of either population.
What Happens Next?
The immediate focus is on Labour’s one-week ultimatum to Green councillors involved in joint administrations.
If the councillors issue the requested rejection of the motion, the parties may be able to preserve some existing arrangements, although political tensions are likely to remain.
If they refuse, Labour has threatened to end the relevant coalitions, potentially creating uncertainty for local councils and their governing arrangements.
Meanwhile, Polanski faces continuing pressure to explain how his party will protect Jewish members while maintaining its position on Palestinian rights.
The controversy may also influence the Green Party’s internal debate about how conference motions are developed, amended and adopted. Critics have argued that a relatively limited proportion of the party’s overall membership participated in the vote, raising questions about how major policy decisions should be made.
Any future review could examine whether the party’s procedures provide sufficient opportunities for debate and whether safeguards are adequate when decisions have significant consequences for minority communities.
Conclusion
Labour’s ultimatum to the Greens marks a significant escalation in the dispute over Zack Polanski’s party and its controversial position on Zionism.
The motion has exposed divisions within the Green Party, provoked strong criticism from Jewish organisations and threatened political cooperation between Labour and the Greens in local government.
For Labour, the immediate issue is whether Green councillors will formally reject the motion and whether existing governing arrangements can continue. For Polanski, the challenge is to demonstrate that support for Palestinian rights can coexist with meaningful protections against antisemitism and discrimination.
The controversy also highlights the difficulty of discussing Israel and Palestine in British politics. Legitimate criticism of a government must remain possible, but political parties must also consider how their language and policies affect communities that may feel targeted or excluded.
Ultimately, the outcome will depend on whether the parties can address the substantive concerns rather than allowing the dispute to deepen indefinitely. The coming days will reveal whether Labour’s ultimatum leads to a formal break in local cooperation or prompts the Greens to take further steps to reassure critics and protect their Jewish members.
