British Jewish Community Gravitating to Greens and Reform UK as Backing for Major Parties Declines

Findings show a emerging electoral split across British Jews, with backing rising fast for the Greens – driven by younger and anti-Israel Jews – while older Orthodox men favor the Reform Party as confidence in the two main parties “plummets”.

Backing of Labour and the Conservatives among UK Jewish voters had fallen to 58% by July 2025 from nearly 84% in 2020, according to a analysis from a prominent policy organization, which commented it was “the weakest support we’ve documented by a significant margin”.

Generally, Labour has been preferred by more “less observant” Jews while the Conservative party is conventionally backed by more “religious” Jews.

Meanwhile, roughly 18% of Jewish individuals in Britain (18%) were favoring the Green Party by summer 2025 – which analysts called “contradictory” given its policy on the Israeli state, which it labeled an “apartheid state” in a vote at its 2024 party conference.

Support for the Green Party grew 9% among UK Jewish voters between the summer 2024 election and June 2025, outstripping the 1% rise in approval of the Green Party among the wider electorate over the same period, and predating the leadership of a leading politician who describes himself as a “committed” Jew but “non-Zionist”.

The study stated the increase in Green Party support indicated “for a notable portion of Jews, domestic priorities and forward-thinking principles outweigh global matters”.

At the same time, approval of Reform increased among the Jewish community from 3% in summer 2024 to 11% in June 2025. However the rise fell behind the 14% jump Reform UK enjoyed with the general public.

“The community is less likely [than the wider electorate] to support Reform UK [11% vs 28%], but more prone to vote for the Greens [18% vs 7%],” the report commented.

A lead analyst remarked: “Reform is more inclined to appeal to men, older, orthodox, and pro-Israel Jews; the Green Party are more prone to draw younger, secular and non-Zionist …[but] it is crucial to note that it is also an element of a broader, broader shift affecting the British public as a whole.”

Still, the “sharp rise in Jewish support for the Reform Party – a party whose language on migration and patriotism would usually be anticipated to distance minority communities, including Jews” was described as “notable” by researchers.

“Notable portions of the Jewish community may lean towards parties pledging resolve and direction, irrespective of political history” when traditional groups were viewed as “indecisive or unfriendly”, it added.

The study stated: “For the earliest occasion in recent British Jewish experience, backing of the two main parties together has declined to less than 60%.

“Given that this is reflected in wider society too, it is not just a data outlier – it may signal a structural shift in Jewish electoral behavior.

“Three forces are driving this division: the Middle East hostilities and its divisive impact on Jewish attitudes; increasing hostility towards Jews, resulting in a major security breach at a religious center; and a broader erosion of faith in established parties.

“In combination, these issues are guiding Jews to political groups that provide direction – either via populism or extreme liberalism.

“If recent developments persist … British Jews are expected to become more politically polarised, leading to additional divisions within the community.”

The research body, which follows population shifts, interviewed 11,000 Jewish residents of Britain for the study, named The decline of dual-party dominance? New developments in the political preferences of British Jews.

It revealed that in the previous year, Jewish electors were more inclined than the broader electorate to support the leading parties, with 44% backing the Labour Party, versus 34% of the electorate as a whole, and 32% backing the Conservative Party, versus 24% of the wider electorate.

By summer, support for Labour had slumped by 13% among UK Jewish voters, compared with a 9% drop with the broader voter base, while backing for the Conservatives among UK Jewish voters dropped by 4%, matching the wider electorate. “Minimal and steady” support for the Lib Dems has moved from 8% to 9% among British Jews.
