UK Jews Gravitating to Green Party and Reform UK as Backing for Major Parties Drops

Research has uncovered a new electoral split within the UK Jewish community, with support increasing rapidly for the Greens – propelled by newer generation and “anti-Zionist” Jews – while older Orthodox men favor Reform UK as trust in the dominant political groups “collapses”.

Backing of the two major UK parties among British Jews had fallen to 58% by summer 2025 from nearly 84% in 2020, according to a report from a leading demographic center, which commented it was “the smallest share we’ve documented by a wide gap”.

Traditionally, Labour is supported by more “less observant” Jews while the Conservatives is traditionally backed by more “religious” Jews.

At the same time, roughly one in five Jewish individuals in Britain (18%) were supporting the Greens by summer 2025 – which researchers labeled “contradictory” given its position on Israel, which it termed an “segregationist regime” in a vote at its 2024 Manchester conference.

Backing of the Green Party rose 9% among UK Jewish voters between August 2024’s general election and June 2025, outstripping the 1% growth in approval of the Green Party among the general public over the identical timeframe, and predating the direction of a prominent member who states he is a “proud” Jew but “not a Zionist”.

The study said the growth in Green Party support indicated “for a sizable segment of Jews, national issues and liberal ideals take precedence over global matters”.

At the same time, backing of Reform UK rose among UK Jewish voters from 3% in summer 2024 to 11% in the following year. But the rise fell behind the 14% rise Reform experienced with the wider electorate.

“Jewish voters are less likely [than the general population] to support the Reform Party [11% vs 28%], but more inclined to vote for the Green party [18% vs 7%],” the analysis commented.

A prominent expert remarked: “Reform UK is more prone to attract male, elderly, orthodox, and Zionist Jews; the Greens are more likely to appeal to youthful, secular and anti-Zionist …[but] it is important to note that it is also part of a larger, more general trend driving the national electorate as a entirety.”

Still, the “rapid increase in approval among the Jewish community for the Reform Party – a party whose discourse on border policy and national identity would typically be expected to estrange ethnic groups, like Jews” was described as “remarkable” by analysts.

“Significant parts of the Jewish population may gravitate toward leaders offering firmness and direction, irrespective of ideological baggage” when traditional groups were perceived as “weak or opposed”, it commented.

The analysis said: “For the earliest occasion in contemporary UK Jewish experience, approval of the Conservative and Labour parties collectively has fallen below 60%.

“Given that this is mirrored in the broader public too, it is not just a data outlier – it may suggest a fundamental change in the political views of Jews.

“Multiple drivers are fueling this fragmentation: the Middle East hostilities and its polarising effect on community views; increasing hostility towards Jews, resulting in a major violent incident at a synagogue; and a broader loss of confidence in established parties.

“Collectively, these elements are pushing Jews in the direction of organizations that deliver direction – whether through mass rhetoric or far-left ideals.

“If recent developments endure … British Jews are likely to become increasingly divided, leading to more strain among Jewish groups.”

The research body, which tracks community changes, polled 11,000 British Jews for the report, called The decline of dual-party dominance? Recent shifts in the political preferences of British Jews.

It revealed that in the previous year, the Jewish community were more likely than the wider public to support the dominant groups, with 44% favoring the Labour Party, versus 34% of the general public, and 32% voting for Conservative, versus 24% of the general population.

By summer, support for the Labour Party had slumped by 13% among the Jewish community, versus a 9% decrease with the wider electorate, while approval of the Tories among British Jews fell by 4%, matching the wider electorate. “Small and consistent” approval of the Liberal Democrats has shifted from 8% to 9% among the Jewish community.
