British Jews Turning to Green Party and Reform Party as Support for Major Parties Drops

Research has uncovered a emerging electoral split within Jewish people in Britain, with backing increasing rapidly for the Green Party – buoyed up by newer generation and anti-Israel Jews – while elderly observant men turn to Reform UK as trust in the dominant political groups “plummets”.

Approval of the two major UK parties among the Jewish community in Britain had declined to 58% by summer 2025 from nearly 84% in 2020, based on a study from a prominent demographic center, which stated it was “the weakest support we’ve ever recorded by a significant margin”.

Labour is typically supported by more “secular” Jews while the Tories is conventionally backed by more “observant” Jews.

At the same time, nearly a fifth of Jewish individuals in Britain (18%) were backing the Green party by June 2025 – which analysts described as “paradoxical” given its policy on Israel, which it described an “segregationist regime” in a decision at its 2024 party conference.

Backing of the Green party grew 9% among the Jewish community between August 2024’s general election and June 2025, outstripping the 1% growth in backing for the Greens among the general public over the same period, and coming before the guidance of a leading figure who states he is a “proud” Jew but “not a Zionist”.

The report noted the rise in Green Party support indicated “for a sizable segment of Jews, home affairs and liberal ideals outweigh foreign policy concerns”.

At the same time, support for the Reform Party grew among the Jewish community from 3% in the 2024 election to 11% in June 2025. But the growth trailed the 14% increase the Reform Party received with the broader voter base.

“The community is less likely [than the general population] to vote for the Reform Party [11% vs 28%], but more prone to vote for the Green party [18% vs 7%],” the analysis stated.

A prominent expert said: “Reform is more prone to appeal to male, elderly, observant, and Zionist Jews; the Greens are more inclined to draw younger, non-religious and anti-Israel …[but] it is crucial to acknowledge that it is also a component of a larger, wider pattern driving the national electorate as a whole.”

Still, the “surge in Jewish support for the Reform Party – a party whose rhetoric on immigration and patriotism would typically be anticipated to estrange minority communities, including Jews” was labeled “remarkable” by analysts.

“Significant parts of the Jewish electorate may move toward parties promising firmness and certainty, irrespective of ideological baggage” when established parties were seen as “indecisive or hostile”, it noted.

The report said: “For the earliest occasion in recent Jewish community history, approval of the two main parties combined has dropped under 60%.

“Given that this is reflected in wider society too, it is not just a numerical irregularity – it may indicate a fundamental change in the political views of Jews.

“Multiple drivers appear to be driving this splintering: the Middle East hostilities and its splitting influence on Jewish opinions; growing anti-Jewish sentiment, peaking with a notable terrorist attack at a religious center; and a wider collapse of trust in mainstream parties.

“Together, these elements are driving Jews in the direction of political groups that deliver clarity – be it through populism or radical progressivism.

“If current trends continue … the UK Jewish community are predicted to become more politically polarised, prompting additional strain among Jewish groups.”

The organization, which monitors population shifts, polled 11,000 British Jews for the analysis, titled The decline of dual-party dominance? Emerging changes in the voting patterns of UK Jewish voters.

It revealed that in the previous year, Jewish electors were more inclined than the general population to back the two main parties, with 44% supporting Labour, against 34% of the total voters, and 32% supporting the Conservative Party, versus 24% of the broader public.

By June, support for the Labour Party had declined by 13% among British Jews, compared with a 9% decrease with the broader voter base, while Conservative support among UK Jewish voters fell by 4%, equaling the general public. “Low and stable” approval of the Liberal Democrats has changed from 8% to 9% among UK Jewish voters.
