British Jewish Community Turning to Green Party and Reform Party as Backing for Main Parties Declines

Research has uncovered a new political divide within the UK Jewish community, with backing rising fast for the Greens – driven by newer generation and anti-Israel Jews – while older observant men favor Reform UK as confidence in the dominant political groups “collapses”.

Backing of Labour and the Conservatives among the Jewish community in Britain had declined to 58% by mid-2025 from almost 84% in 2020, according to a study from a respected demographic center, which noted it was “the lowest level we’ve observed by a wide gap”.

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

At the same time, nearly 18% of UK Jewish voters (18%) were supporting the Green party by mid-2025 – which researchers described as “contradictory” given its policy on the Israeli state, which it labeled an “segregationist regime” in a vote at its 2024 national meeting.

Support for the Green Party rose 9% among the Jewish community between the summer 2024 election and the following year, outstripping the 1% increase in Green support among the wider electorate over the same period, and predating the leadership of a leading politician who states he is a “proud” Jew but “not a Zionist”.

The report stated the growth in Green party support implied “for a notable portion of Jews, domestic priorities and forward-thinking principles surpass international affairs”.

In contrast, support for Reform rose among British Jews from 3% in August 2024 to 11% in the following year. But the growth trailed the 14% increase Reform UK enjoyed with the general public.

“Jews remain less likely [than the general population] to support Reform UK [11% vs 28%], but more inclined to support the Greens [18% vs 7%],” the analysis said.

A senior researcher remarked: “Reform is more prone to attract men, older, observant, and pro-Israel Jews; the Green Party are more likely to attract youthful, non-religious and anti-Israel …[but] it is crucial to acknowledge that it is also part of a wider, more general trend influencing the British public as a complete group.”

Nonetheless, the “surge in Jewish support for the Reform Party – a party whose discourse on migration and patriotism would usually be expected to estrange minority communities, such as Jews” was described as “remarkable” by analysts.

“Notable portions of the Jewish electorate may gravitate toward voices pledging firmness and certainty, regardless of political history” when traditional groups were perceived as “ineffective or opposed”, it commented.

The analysis stated: “For the earliest occasion in contemporary UK Jewish history, backing of the Labour and Conservative parties combined 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 systemic transformation in the political views of Jews.

“Multiple drivers appear to be driving this fragmentation: the war in Gaza and its splitting influence on community views; increasing hostility towards Jews, resulting in a recent security breach at a Jewish house of worship; and a broader erosion of faith in traditional political groups.

“In combination, these elements are driving Jews in the direction of political groups that provide direction – either via populism or far-left ideals.

“If current trends persist … the UK Jewish community are predicted to become further split, causing more divisions within the community.”

The study group, which monitors demographic trends, surveyed 11,000 Jewish residents of Britain for the study, titled The shift away from two-party support? New developments in the political preferences of UK Jewish voters.

It found that in the previous year, Jewish voters were more inclined than the broader electorate to back the leading parties, with 44% backing Labour, compared with 34% of the total voters, and 32% supporting Conservative, against 24% of the broader public.

By mid-year, backing of the Labour Party had dropped by 13% among British Jews, against a 9% drop with the general public, while Conservative support among the Jewish community fell by 4%, paralleling the broader population. “Low and stable” backing of the Liberal Democrats has moved from 8% to 9% among British Jews.
