British Jews Turning to Greens and Reform UK as Backing for Main Parties Falls

Research has uncovered a fresh political divide among British Jews, with approval increasing rapidly for the Greens – driven by newer generation and “anti-Zionist” Jews – while elderly observant men favor the Reform Party as faith in the dominant political groups “plummets”.

Backing of the two major UK parties among the Jewish community in Britain had dropped to 58% by mid-2025 from around 84% in 2020, based on a analysis from a respected policy organization, which noted it was “the smallest share we’ve ever recorded by a significant margin”.

Traditionally, Labour is favored by more “less observant” Jews while the Tories is historically backed by more “Orthodox” Jews.

At the same time, roughly 18% of British Jews (18%) were supporting the Green Party by summer 2025 – which analysts called “surprising” given its position on the Israeli state, which it described an “discriminatory system” in a decision at its 2024 national meeting.

Backing of the Green party grew 9% among UK Jewish voters between August 2024’s general election and mid-2025, outstripping the 1% increase in approval of the Green Party among the wider electorate over the equivalent interval, and preceding the direction of a well-known member who states he is a “proud” Jew but “anti-Zionist”.

The study noted the growth in Green party support suggested “for a significant minority of Jews, domestic priorities and liberal ideals take precedence over international affairs”.

At the same time, approval of Reform increased among the Jewish community from 3% in August 2024 to 11% in June 2025. However the growth trailed the 14% increase Reform received with the general public.

“Jews remain less prone [than the general population] to back Reform [11% vs 28%], but more prone to back the Green Party [18% vs 7%],” the study said.

A lead analyst noted: “Reform is more inclined to attract men, older, traditional, and Zionist Jews; the Green Party are more likely to draw newer generation, non-religious and anti-Zionist …[but] it is essential to note that it is also part of a broader, broader shift affecting the UK population as a entirety.”

Nonetheless, the “rapid increase in approval among the Jewish community for Reform UK – a party whose rhetoric on border policy and nationalism would typically be anticipated to distance diverse populations, such as Jews” was labeled “notable” by researchers.

“Notable portions of the Jewish population may lean towards parties pledging strength and clarity, despite political history” when established parties were seen as “indecisive or hostile”, it commented.

The report said: “For the initial instance in contemporary Jewish community experience, support for the two main parties combined has fallen below 60%.

“Given that this is mirrored in the broader public too, it is not just a data outlier – it may indicate a structural shift in the political views of Jews.

“Several factors are propelling this division: the war in Gaza and its splitting influence on community views; rising antisemitism, resulting in a notable security breach at a synagogue; and a wider erosion of faith in established parties.

“In combination, these factors are pushing Jews to political groups that deliver certainty – either via mass rhetoric or radical progressivism.

“If current trends persist … British Jews are likely to become more politically polarised, causing further divisions within the community.”

The study group, which tracks demographic trends, surveyed 11,000 British Jews for the study, named The decline of dual-party dominance? New developments in the voting patterns of UK Jewish voters.

It revealed that in the election year, the Jewish community were more prone than the general population to back the leading parties, with 44% backing Labour, compared with 34% of the electorate as a whole, and 32% supporting Conservative, versus 24% of the wider electorate.

By mid-year, support for Labour had dropped by 13% among UK Jewish voters, against a 9% decrease with the broader voter base, while backing for the Conservatives among British Jews fell by 4%, matching the general public. “Low and stable” support for the Lib Dems has shifted from 8% to 9% among UK Jewish voters.
