British Jewish Community Shifting Towards Green Party and Reform Party as Backing for Main Parties Declines

Studies reveal a new electoral split across British Jews, with approval rising fast for the Greens – buoyed up by youthful and anti-Israel Jews – while elderly traditional men favor Reform UK as confidence in the two main parties “collapses”.

Backing of the two major UK parties among the Jewish community in Britain had fallen to 58% by mid-2025 from almost 84% in 2020, as per a study from a leading policy organization, which commented it was “the lowest level we’ve documented by a significant margin”.

Generally, Labour has been favored by more “secular” Jews while the Conservatives is conventionally backed by more “observant” Jews.

At the same time, almost a fifth of Jewish individuals in Britain (18%) were favoring the Green party by mid-2025 – which analysts described as “paradoxical” given its position on Israel, which it labeled an “segregationist regime” in a resolution at its 2024 Manchester conference.

Approval of the Green Party rose 9% among the Jewish community between the summer 2024 election and mid-2025, outstripping the 1% rise in backing for the Greens among the general public over the equivalent interval, and coming before the leadership of a leading politician who states he is a “devout” Jew but “anti-Zionist”.

The analysis said the increase in Greens support suggested “for a sizable segment of Jews, home affairs and progressive values surpass international affairs”.

In contrast, backing of the Reform Party rose among British Jews from 3% in summer 2024 to 11% in June 2025. Yet the rise fell behind the 14% jump the Reform Party received with the general public.

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

A senior researcher said: “Reform is more prone to appeal to male, elderly, orthodox, and Zionist Jews; the Green Party are more likely to appeal to younger, non-religious and anti-Israel …[but] it is important to acknowledge that it is also part of a larger, more general trend driving the national electorate as a entirety.”

Nonetheless, the “surge in Jewish support for the Reform Party – a political group whose language on migration and national identity would typically be expected to alienate ethnic groups, such as Jews” was called “striking” by researchers.

“Large segments of the Jewish population may move toward leaders offering strength and clarity, irrespective of ideological baggage” when mainstream parties were perceived as “weak or hostile”, it added.

The report stated: “For the first time in contemporary British Jewish experience, support for the Conservative and Labour parties together has declined to less than 60%.

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

“Several factors appear to be driving this fragmentation: the Middle East hostilities and its polarising effect on Jewish opinions; growing anti-Jewish sentiment, resulting in a major violent incident at a synagogue; and a more general collapse of trust in traditional political groups.

“Collectively, these elements are guiding Jews in the direction of organizations that deliver clarity – either via populism or extreme liberalism.

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

The study group, which monitors community changes, polled 11,000 UK Jewish individuals for the report, titled The decline of dual-party dominance? Recent shifts in the voting patterns of the Jewish community.

It discovered that in the election year, Jewish voters were more inclined than the wider public to support the leading parties, with 44% supporting Labour, against 34% of the total voters, and 32% voting for Conservative, compared with 24% of the broader public.

By June, backing of the Labour Party had slumped by 13% among UK Jewish voters, versus a 9% decrease with the general public, while backing for the Conservatives among UK Jewish voters fell by 4%, matching the general public. “Small and consistent” backing of the Liberal Democrats has moved from 8% to 9% among British Jews.
