UK Jewish Community Gravitating to Green Party and Reform UK as Support for Major Parties Declines

Research has uncovered a new party division across Jewish people in Britain, with support rising fast for the Green Party – driven by newer generation and non-Zionist Jews – while more senior traditional men lean toward the Reform Party as faith in the two main parties “collapses”.

Support for the Conservative and Labour parties among UK Jewish voters had fallen to 58% by summer 2025 from nearly 84% in 2020, according to a report from a prominent research institute, which noted it was “the smallest share we’ve documented by some distance”.

Labour is typically favored by more “secular” Jews while the Tories is historically backed by more “religious” Jews.

Meanwhile, roughly one in five UK Jewish voters (18%) were supporting the Green party by mid-2025 – which analysts described as “contradictory” given the party’s stance on Israel, which it labeled an “discriminatory system” in a vote at its 2024 party conference.

Support for the Green party rose 9% among British Jews between August 2024’s general election and the following year, exceeding the 1% increase in approval of the Green Party among the general public over the same period, and preceding the guidance of a leading politician who states he is a “proud” Jew but “not a Zionist”.

The study said the rise in Green party support suggested “for a significant minority of Jews, domestic priorities and progressive values outweigh international affairs”.

Meanwhile, backing of the Reform Party increased among British Jews from 3% in August 2024 to 11% in mid-2025. Yet the increase lagged the 14% rise Reform UK experienced with the general public.

“Jewish voters are less inclined [than the general population] to support Reform UK [11% vs 28%], but more prone to vote for the Greens [18% vs 7%],” the report commented.

A prominent expert said: “Reform is more prone to attract men, older, traditional, and pro-Israel Jews; the Green Party are more inclined to appeal to youthful, unaffiliated and non-Zionist …[but] it is important to recognize that it is also an element of a wider, more general trend influencing the British public as a whole.”

Still, the “sharp rise in Jewish support for Reform UK – a organization whose rhetoric on immigration and national identity would usually be anticipated to estrange ethnic groups, including Jews” was labeled “remarkable” by analysts.

“Notable portions of the Jewish population may gravitate toward leaders pledging strength and direction, regardless of political history” when established parties were seen as “ineffective or opposed”, it noted.

The analysis declared: “For the earliest occasion in recent UK Jewish experience, approval of the Labour and Conservative parties collectively has dropped under 60%.

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

“Three forces are propelling this splintering: the war in Gaza and its splitting influence on community views; rising antisemitism, culminating in a notable security breach at a Jewish house of worship; and a broader collapse of trust in established parties.

“Together, these issues are driving Jews to organizations that offer clarity – whether through mass rhetoric or far-left ideals.

“If ongoing changes continue … the UK Jewish community are predicted to become more politically polarised, prompting more divisions within the community.”

The study group, which monitors demographic trends, interviewed 11,000 British Jews for the report, called The decline of dual-party dominance? Recent shifts in the voting patterns of British Jews.

It discovered that in the election year, the Jewish community were more inclined than the broader electorate to back the dominant groups, with 44% supporting Labour, versus 34% of the electorate as a whole, and 32% backing the Conservative Party, against 24% of the broader public.

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