British Jews Shifting Towards Green Party and Reform Party as Backing for Major Parties Declines

Research has uncovered a emerging electoral split across British Jews, with backing increasing rapidly for the Greens – propelled by newer generation and “anti-Zionist” Jews – while older Orthodox men favor the Reform Party as faith in the dominant political groups “drops sharply”.

Approval of the Conservative and Labour parties among UK Jewish voters had declined to 58% by summer 2025 from around 84% in 2020, based on a analysis from a respected research institute, which commented it was “the lowest level we’ve documented by a wide gap”.

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

In parallel, almost a fifth of Jewish individuals in Britain (18%) were supporting the Greens by summer 2025 – which analysts called “contradictory” given the party’s stance on Israel, which it labeled an “discriminatory system” in a vote at its 2024 Manchester conference.

Support for the Green party increased 9% among UK Jewish voters between August 2024’s general election and mid-2025, outstripping the 1% increase in Green support among the general public over the same period, and preceding the guidance of a prominent member who describes himself as a “committed” Jew but “non-Zionist”.

The study noted the increase in Green Party support suggested “for a notable portion of Jews, national issues and progressive values surpass foreign policy concerns”.

Meanwhile, backing of the Reform Party increased among UK Jewish voters from 3% in summer 2024 to 11% in mid-2025. However the increase lagged the 14% increase Reform UK experienced with the wider electorate.

“The community is less prone [than the wider electorate] to back the Reform Party [11% vs 28%], but more inclined to vote for the Green Party [18% vs 7%],” the report commented.

A prominent expert said: “The Reform Party is more inclined to appeal to male, older, orthodox, and pro-Israel Jews; the Green Party are more inclined to draw newer generation, non-religious and anti-Zionist …[but] it is important to acknowledge that it is also part of a broader, more general trend affecting the national electorate as a complete group.”

Nonetheless, the “surge in backing from Jews for the Reform Party – a political group whose rhetoric on immigration and national identity would typically be predicted to estrange diverse populations, including Jews” was called “notable” by researchers.

“Large segments of the Jewish population may gravitate toward parties promising firmness and direction, regardless of political history” when mainstream parties were viewed as “indecisive or hostile”, it added.

The report said: “For the first time in recent UK Jewish experience, support for the two main parties together has dropped under 60%.

“Given that this is seen in wider society too, it is not just a statistical anomaly – it may signal a fundamental change in Jewish electoral behavior.

“Multiple drivers seem to be propelling this division: the Gaza conflict and its divisive impact on Jewish opinions; growing anti-Jewish sentiment, peaking with a notable violent incident at a synagogue; and a wider erosion of faith in mainstream parties.

“Collectively, these issues are pushing Jews in the direction of organizations that deliver certainty – either via popular appeal or radical progressivism.

“If recent developments continue … British Jews are likely to become increasingly divided, prompting more internal community tensions.”

The research body, which monitors demographic trends, surveyed 11,000 UK Jewish individuals for the study, titled The shift away from two-party support? Recent shifts in the voting patterns of UK Jewish voters.

It discovered that in the election year, Jewish voters were more prone than the wider public to support the two main parties, with 44% supporting Labour, compared with 34% of the total voters, and 32% backing Conservative, versus 24% of the general population.

By mid-year, backing of the Labour Party had dropped by 13% among the Jewish community, against a 9% decline with the wider electorate, while Conservative support among UK Jewish voters declined by 4%, equaling the broader population. “Small and consistent” support for the Liberal Democrats has changed from 8% to 9% among UK Jewish voters.
