British Jews Turning to Greens and Reform Party as Support for Main Parties Drops

Research has uncovered a emerging electoral split among the UK Jewish community, with support increasing rapidly for the Greens – driven by younger and anti-Israel Jews – while more senior traditional men lean toward the Reform Party as confidence in the two main parties “plummets”.

Backing of the two major UK parties among UK Jewish voters had declined to 58% by July 2025 from nearly 84% in 2020, as per a study from a prominent policy organization, which noted it was “the smallest share we’ve documented by a wide gap”.

Traditionally, Labour is preferred by more “secular” Jews while the Conservatives is historically backed by more “religious” Jews.

Meanwhile, roughly 18% of British Jews (18%) were favoring the Greens by summer 2025 – which the study called “contradictory” given its policy on the Israeli state, which it termed an “discriminatory system” in a decision at its 2024 Manchester conference.

Support for the Green party rose 9% among British Jews between the summer 2024 election and the following year, surpassing the 1% rise in approval of the Green Party among the wider electorate over the same period, and predating the direction of a prominent politician who identifies as a “proud” Jew but “anti-Zionist”.

The study said the rise in Green party support suggested “for a significant minority of Jews, national issues and liberal ideals take precedence over global matters”.

At the same time, support for Reform UK rose among British Jews from 3% in August 2024 to 11% in the following year. But the increase lagged the 14% jump Reform UK received with the wider electorate.

“The community is less likely [than the wider electorate] to vote for Reform UK [11% vs 28%], but more inclined to back the Greens [18% vs 7%],” the study stated.

A lead analyst noted: “Reform UK is more inclined to appeal to men, more senior, traditional, and Zionist Jews; the Green Party are more inclined to appeal to newer generation, non-religious and anti-Israel …[but] it is crucial to acknowledge that it is also a component of a larger, more general trend influencing the British public as a whole.”

Nonetheless, the “surge in approval among the Jewish community for the Reform Party – a political group whose discourse on migration and nationalism would normally be predicted to estrange ethnic groups, including Jews” was labeled “notable” by researchers.

“Large segments of the Jewish electorate may gravitate toward parties promising firmness and clarity, irrespective of political history” when established parties were viewed as “ineffective or opposed”, it commented.

The report said: “For the initial instance in contemporary Jewish community records, backing of the Conservative and Labour parties together has declined to less than 60%.

“Given that this is mirrored in the general population too, it is not just a numerical irregularity – it may signal a systemic transformation in the political views of Jews.

“Several factors appear to be propelling this division: the Gaza conflict and its divisive impact on community views; increasing hostility towards Jews, resulting in a recent violent incident at a synagogue; and a broader erosion of faith in established parties.

“Collectively, these elements are pushing Jews toward political groups that deliver clarity – be it through popular appeal or far-left ideals.

“If ongoing changes persist … British Jews are predicted to become further split, causing more strain among Jewish groups.”

The research body, which follows population shifts, polled 11,000 British Jews for the report, called The shift away from two-party support? Emerging changes in the political preferences of the Jewish community.

It found that in the election year, Jewish voters were more prone than the wider public to vote for the dominant groups, with 44% supporting the Labour Party, versus 34% of the general public, and 32% backing Conservative, versus 24% of the wider electorate.

By summer, approval of Labour had declined by 13% among UK Jewish voters, compared with a 9% decline with the broader voter base, while approval of the Tories among the Jewish community declined by 4%, paralleling the broader population. “Low and stable” backing of the Lib Dems has moved from 8% to 9% among the Jewish community.
