British Jews Shifting Towards Greens and Reform Party as Support for Major Parties Declines

Findings show a fresh political divide among Jewish people in Britain, with backing increasing rapidly for the Greens – propelled by newer generation and “anti-Zionist” Jews – while elderly observant men lean toward the Reform Party as faith in the leading parties “plummets”.

Backing of the Conservative and Labour parties among British Jews had fallen to 58% by mid-2025 from nearly 84% in 2020, based on a report from a prominent research institute, which commented it was “the smallest share we’ve observed by some distance”.

Generally, Labour has been favored by more “non-religious” Jews while the Conservatives is conventionally preferred by more “observant” Jews.

Meanwhile, nearly 18% of Jewish individuals in Britain (18%) were supporting the Greens by June 2025 – which the study called “surprising” given the party’s stance on Israel, which it termed an “segregationist regime” in a vote at its 2024 national meeting.

Backing of the Green party rose 9% among UK Jewish voters between the summer 2024 election and June 2025, surpassing the 1% growth in Green support among the broader voting population over the equivalent interval, and predating the leadership of a leading figure who describes himself as a “proud” Jew but “not a Zionist”.

The analysis stated the growth in Green Party support indicated “for a sizable segment of Jews, home affairs and forward-thinking principles outweigh global matters”.

At the same time, backing of the Reform Party grew among the Jewish community from 3% in summer 2024 to 11% in the following year. But the rise trailed the 14% rise the Reform Party received with the wider electorate.

“Jewish voters are less prone [than the broader public] to back Reform [11% vs 28%], but more likely to support the Green Party [18% vs 7%],” the report said.

A senior researcher said: “Reform is more likely to appeal to male, elderly, observant, and Zionist Jews; the Greens are more likely to attract youthful, secular and anti-Israel …[but] it is essential to note that it is also a component of a larger, wider pattern influencing the British public as a whole.”

However, the “sharp rise in approval among the Jewish community for Reform UK – a organization whose language on border policy and patriotism would typically be predicted to distance diverse populations, like Jews” was labeled “striking” by researchers.

“Significant parts of the Jewish population may gravitate toward voices offering resolve and certainty, regardless of past associations” when traditional groups were perceived as “indecisive or opposed”, it added.

The analysis stated: “For the earliest occasion in recent British Jewish history, support for the Labour and Conservative parties collectively has fallen below 60%.

“Given that this is mirrored in the broader public too, it is not just a numerical irregularity – it may suggest a structural shift in Jewish electoral behavior.

“Several factors seem to be driving this division: the war in Gaza and its divisive impact on Jewish opinions; increasing hostility towards Jews, peaking with a recent terrorist attack at a synagogue; and a wider collapse of trust in established parties.

“Together, these factors are guiding Jews in the direction of political groups that provide direction – either via popular appeal or radical progressivism.

“If ongoing changes continue … the UK Jewish community are expected to become further split, leading to more internal community tensions.”

The research body, which tracks demographic trends, interviewed 11,000 British Jews for the study, named The end of two-party politics? Emerging changes in the voting patterns of British Jews.

It found that in the election year, the Jewish community were more inclined than the general population to vote for the two main parties, with 44% backing the Labour Party, versus 34% of the general public, and 32% backing Conservative, against 24% of the wider electorate.

By summer, approval of the Labour Party had declined by 13% among UK Jewish voters, versus a 9% drop with the broader voter base, while Conservative support among British Jews dropped by 4%, matching the general public. “Small and consistent” approval of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
