UK Jews Gravitating to Greens and Reform Party as Backing for Main Parties Falls

Findings show a fresh electoral split across the UK Jewish community, with approval growing quickly for the Greens – driven by newer generation and non-Zionist Jews – while older observant men turn to the Reform Party as faith in the dominant political groups “collapses”.

Support for Labour and the Conservatives among UK Jewish voters had declined to 58% by summer 2025 from around 84% in 2020, as per a study from a prominent demographic center, which stated it was “the lowest level we’ve ever recorded by some distance”.

Labour is typically supported by more “non-religious” Jews while the Conservatives is conventionally favored by more “observant” Jews.

Meanwhile, nearly one in five Jewish individuals in Britain (18%) were favoring the Green party by summer 2025 – which researchers described as “surprising” given its policy on Israel, which it termed an “apartheid state” in a vote at its 2024 party conference.

Approval of the Green Party grew 9% among UK Jewish voters between the 2024 general election and mid-2025, exceeding the 1% rise in Green support among the general public over the same period, and coming before the leadership of a prominent member who states he is a “devout” Jew but “not a Zionist”.

The report noted the growth in Green Party support implied “for a sizable segment of Jews, domestic priorities and liberal ideals take precedence over global matters”.

Meanwhile, support for the Reform Party increased among the Jewish community from 3% in the 2024 election to 11% in the following year. But the rise lagged the 14% jump Reform UK enjoyed with the broader voter base.

“Jewish voters are less prone [than the broader public] to back the Reform Party [11% vs 28%], but more likely to vote for the Green party [18% vs 7%],” the study stated.

A lead analyst said: “Reform UK is more inclined to draw men, older, orthodox, and pro-Israel Jews; the Green Party are more inclined to attract younger, non-religious and non-Zionist …[but] it is essential to note that it is also a component of a wider, wider pattern influencing the UK population as a whole.”

Nonetheless, the “rapid increase in backing from Jews for Reform UK – a party whose language on border policy and nationalism would typically be anticipated to estrange ethnic groups, like Jews” was described as “striking” by analysts.

“Significant parts of the Jewish community may gravitate toward leaders pledging firmness and certainty, regardless of political history” when established parties were seen as “indecisive or hostile”, it added.

The study said: “For the initial instance in contemporary Jewish community history, backing of the two main parties collectively has declined to less than 60%.

“Given that this is seen in the general population too, it is not just a data outlier – it may indicate a fundamental change in Jewish political identity.

“Several factors appear to be fueling this splintering: the Gaza conflict and its polarising effect on community views; rising antisemitism, culminating in a notable violent incident at a synagogue; and a more general erosion of faith in mainstream parties.

“Together, these factors are pushing Jews toward organizations that offer certainty – be it through popular appeal or far-left ideals.

“If recent developments continue … British Jews are predicted to become further split, causing further divisions within the community.”

The study group, which tracks demographic trends, interviewed 11,000 Jewish residents of Britain for the analysis, called The end of two-party politics? New developments in the political preferences of British Jews.

It revealed that in 2024, Jewish voters were more prone than the broader electorate to back the dominant groups, with 44% backing the Labour Party, against 34% of the electorate as a whole, and 32% backing the Conservative Party, against 24% of the general population.

By mid-year, support for the Labour Party had slumped by 13% among British Jews, compared with a 9% drop with the wider electorate, while backing for the Conservatives among UK Jewish voters declined by 4%, matching the broader population. “Small and consistent” support for the Liberal Democrats has changed from 8% to 9% among British Jews.
