Jewish Left Faces Isolation as Right Leads Antisemitism Fight 2026

The fight against antisemitism in Britain is undergoing a seismic shift, leaving many on the Jewish left feeling increasingly isolated. As right-wing political figures seize the initiative in condemning anti-Jewish hatred and defending Israel, liberal and progressive Jews are grappling with a painful political realignment. This dynamic was starkly illustrated at a recent central London rally, where Rabbi Charley Baginsky, co-leader of Progressive Judaism, faced boos from the crowd—a stark contrast to the warm reception given to Reform UK's Richard Tice and Conservative leader Kemi Badenoch.

For decades, British Jews found a natural home on the left, rooted in shared values of social justice and community responsibility. However, the Jeremy Corbyn era within the Labour Party severely damaged that trust, a wound that has deepened since the October 7, 2023 attacks in Israel. Many Jewish voters now feel abandoned by Labour over the pace of action against anti-Jewish racism and Islamist extremism, pushing them toward parties like Reform UK, which they perceive as acting more decisively.

The Right's Embrace and the Left's Reckoning

The right's ascendance on this issue is not accidental. Raphi Bloom of the Jewish Representative Council notes that Reform UK has brought over “genuine allies” from the Conservatives—including Suella Braverman and Robert Jenrick—at a time when many feel betrayed. While Reform has had its own issues with anti-Jewish racism, Bloom argues it has “dealt with them swiftly,” a speed that voters are increasingly judging parties by. This has created a political migration where safety and decisive action are prioritized over traditional ideological homes.

Yet, the Jewish left is not monolithic. Many still believe that antisemitism can only be effectively confronted through broad alliances with other minority communities and anti-racist movements. Rabbi Baginsky insists that antisemitism must be placed within the wider context of tackling all forms of hate, saying, “until we are a society that tackles antisemitism, Islamophobia, racism, misogyny, and says ‘this is not the sort of Britain we want’, then we won’t be living in a Britain that’s safe for any of us.” This intersectional approach is increasingly difficult to maintain when parts of those same anti-racist spaces are viewed with suspicion for minimizing hostility toward Jews.

Voting Trends and Community Fractures

The most recent research into the voting preferences of British Jews reveals a complex picture. In 2025, support for the Greens was actually higher than support for Reform. However, among community leaders, there is a clear belief that the right is benefiting from fading trust in the left. The feeling of being jeered off stage at their own rallies, as happened to Rabbis Baginsky and Levy last year outside Downing Street, has left deep scars. Even Liberal Democrat leader Ed Davey faced boos before an MC intervened, highlighting that the ire is directed broadly at the political establishment perceived as failing.

This political fracture has created a painful dilemma for the Jewish left. On one hand, they fear that aligning with the right means sacrificing broader social justice goals. On the other, they feel that their specific safety concerns are being dismissed by traditional allies. As one attendee at the rally noted, the warm reception for right-wing figures reflects a growing sentiment that “the answer is drawing the walls up” rather than building broader coalitions.

What Does the Future Hold?

The path forward for the Jewish left is fraught with challenges. Rabbi Baginsky acknowledges that her message of unity is “a really hard message to give when, for some people, the answer is drawing the walls up.” The community must navigate a landscape where political expediency and moral clarity often clash. Some are choosing to prioritize safety over ideology, while others double down on the belief that only through solidarity with other marginalized groups can true safety be achieved.

For now, the Jewish left finds itself in a precarious position: too left for the right's new coalition, and too Jewish for some parts of the left. The coming years will test whether they can rebuild trust or whether the political realignment will push them further into the margins. What is clear is that the fight against antisemitism can no longer be taken for granted as a left-wing cause—it has become a central political battleground where alliances are shifting rapidly.

Frequently Asked Questions

Why are some Jewish voters moving to the right?

Many Jewish voters feel abandoned by the Labour Party, particularly after the Jeremy Corbyn era and the perceived slow response to antisemitism following the October 7 attacks. They see right-wing parties like Reform UK as acting more swiftly and decisively against anti-Jewish racism, even if those parties have their own controversial histories.

Is the Jewish left completely isolated?

No, but it is under significant strain. Many progressive Jews still believe in building broad anti-racist coalitions. However, they face increasing skepticism from parts of the left that they feel minimize or tolerate hostility toward Jews, while also being booed at their own community events for appearing too centrist or left-leaning.

How does this affect the broader fight against antisemitism?

The shift risks politicizing the fight against antisemitism, making it a partisan issue rather than a universal one. Rabbi Baginsky and others argue that true safety requires tackling all forms of hate together, but the current climate is pushing many toward a more insular, defensive posture. This could weaken the broad alliances needed to combat racism in all its forms.
