British Jews Turning to Greens and Reform UK as Backing for Main Parties Declines

Findings show a emerging political divide across British Jews, with backing increasing rapidly for the Green Party – propelled by youthful and non-Zionist Jews – while more senior traditional men turn to the Reform Party as confidence in the dominant political groups “plummets”.

Support for the Conservative and Labour parties among the Jewish community in Britain had fallen to 58% by July 2025 from nearly 84% in 2020, according to a analysis from a leading demographic center, which noted it was “the lowest level we’ve observed by a significant margin”.

Traditionally, Labour is preferred by more “less observant” Jews while the Tories is historically preferred by more “religious” Jews.

At the same time, nearly a fifth of UK Jewish voters (18%) were favoring the Greens by summer 2025 – which analysts described as “paradoxical” given the party’s stance on the Israeli state, which it labeled an “apartheid state” in a decision at its 2024 national meeting.

Approval of the Green Party rose 9% among UK Jewish voters between the summer 2024 election and June 2025, outstripping the 1% rise in approval of the Green Party among the broader voting population over the equivalent interval, and preceding the direction of a leading member who identifies as a “committed” Jew but “not a Zionist”.

The report noted the growth in Green party support indicated “for a notable portion of Jews, domestic priorities and forward-thinking principles take precedence over global matters”.

At the same time, support for the Reform Party grew among British Jews from 3% in summer 2024 to 11% in June 2025. But the increase trailed the 14% increase the Reform Party experienced with the wider electorate.

“Jews remain less likely [than the general population] to back Reform UK [11% vs 28%], but more prone to vote for the Green party [18% vs 7%],” the analysis said.

A lead analyst noted: “Reform is more inclined to attract men, more senior, traditional, and pro-Israel Jews; the Green Party are more likely to appeal to newer generation, secular and anti-Israel …[but] it is crucial to acknowledge that it is also a component of a wider, broader shift affecting the British public as a complete group.”

Nonetheless, the “rapid increase in Jewish support for Reform – a political group whose rhetoric on border policy and nationalism would normally be predicted to estrange diverse populations, including Jews” was described as “striking” by the study.

“Significant parts of the Jewish community may gravitate toward leaders offering resolve and clarity, irrespective of political history” when established parties were viewed as “weak or unfriendly”, it commented.

The study stated: “For the earliest occasion in modern Jewish community history, support for the Labour and Conservative parties combined has dropped under 60%.

“Given that this is mirrored in the general population too, it is not just a numerical irregularity – it may signal a structural shift in Jewish electoral behavior.

“Multiple drivers appear to be driving this division: the war in Gaza and its splitting influence on Jewish opinions; increasing hostility towards Jews, culminating in a recent security breach at a synagogue; and a broader loss of confidence in established parties.

“Together, these issues are driving Jews in the direction of political groups that provide clarity – be it through populism or far-left ideals.

“If ongoing changes continue … British Jews are expected to become increasingly divided, prompting further internal community tensions.”

The organization, which follows population shifts, interviewed 11,000 British Jews for the analysis, named The decline of dual-party dominance? New developments in the political preferences of the Jewish community.

It discovered that in 2024, Jewish voters were more likely than the general population to vote for the dominant groups, with 44% supporting Labour, versus 34% of the total voters, and 32% backing Conservative, versus 24% of the general population.

By June, approval of Labour had slumped by 13% among UK Jewish voters, versus a 9% decrease with the wider electorate, while backing for the Conservatives among the Jewish community fell by 4%, paralleling the wider electorate. “Minimal and steady” backing of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
