British Jews Shifting Towards Green Party and Reform UK as Support for Major Parties Drops

Studies reveal a new party division across Jewish people in Britain, with support rising fast for the Greens – propelled by younger and anti-Israel Jews – while elderly Orthodox men turn to Reform UK as confidence in the leading parties “plummets”.

Support for the Conservative and Labour parties among British Jews had dropped to 58% by summer 2025 from nearly 84% in 2020, according to a report from a leading demographic center, which stated it was “the weakest support we’ve documented by a significant margin”.

Labour is typically favored by more “less observant” Jews while the Tories is traditionally favored by more “religious” Jews.

Meanwhile, roughly one in five Jewish individuals in Britain (18%) were favoring the Green party by mid-2025 – which the study labeled “surprising” given its policy on the Israeli state, which it termed an “discriminatory system” in a resolution at its 2024 national meeting.

Support for the Green party rose 9% among the Jewish community between the 2024 general election and mid-2025, surpassing the 1% increase in backing for the Greens among the wider electorate over the equivalent interval, and predating the guidance of a leading member who identifies as a “committed” Jew but “not a Zionist”.

The analysis said the rise in Green party support implied “for a notable portion of Jews, domestic priorities and forward-thinking principles surpass international affairs”.

Meanwhile, backing of Reform UK grew among UK Jewish voters from 3% in summer 2024 to 11% in June 2025. However the increase trailed the 14% rise Reform received with the broader voter base.

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

A lead analyst noted: “Reform UK is more inclined to appeal to male, more senior, orthodox, and pro-Israel Jews; the Green Party are more likely to appeal to youthful, unaffiliated and non-Zionist …[but] it is crucial to acknowledge that it is also a component of a larger, more general trend affecting the British public as a whole.”

However, the “sharp rise in Jewish support for Reform UK – a party whose rhetoric on immigration and nationalism would normally be predicted to distance minority communities, such as Jews” was described as “notable” by the study.

“Large segments of the Jewish community may lean towards leaders offering strength and direction, irrespective of past associations” when mainstream parties were perceived as “ineffective or hostile”, it added.

The study stated: “For the initial instance in modern British Jewish experience, backing of the two main parties collectively has dropped under 60%.

“Given that this is seen in wider society too, it is not just a numerical irregularity – it may suggest a structural shift in the political views of Jews.

“Multiple drivers are fueling this splintering: the war in Gaza and its polarising effect on Jewish attitudes; growing anti-Jewish sentiment, resulting in a major violent incident at a Jewish house of worship; and a wider loss of confidence in mainstream parties.

“Collectively, these elements are pushing Jews toward political groups that deliver clarity – either via mass rhetoric or radical progressivism.

“If ongoing changes continue … the UK Jewish community are expected to become more politically polarised, causing additional divisions within the community.”

The organization, which monitors demographic trends, surveyed 11,000 UK Jewish individuals for the study, titled The decline of dual-party dominance? New developments in the political preferences of UK Jewish voters.

It revealed that in the previous year, the Jewish community were more prone than the general population to support the dominant groups, with 44% supporting the Labour Party, versus 34% of the general public, and 32% supporting the Conservative Party, compared with 24% of the broader public.

By mid-year, backing of the Labour Party had dropped by 13% among British Jews, against a 9% decline with the general public, while backing for the Conservatives among the Jewish community fell by 4%, equaling the general public. “Minimal and steady” backing of the Lib Dems has moved from 8% to 9% among UK Jewish voters.
