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

Findings show a new party division within Jewish people in Britain, with backing rising fast for the Greens – propelled by newer generation and anti-Israel Jews – while elderly Orthodox men favor Reform UK as faith in the two main parties “plummets”.

Support for Labour and the Conservatives among UK Jewish voters had declined to 58% by summer 2025 from around 84% in 2020, based on a study from a leading research institute, which stated it was “the smallest share we’ve observed by a wide gap”.

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

At the same time, roughly one in five UK Jewish voters (18%) were favoring the Greens by summer 2025 – which analysts called “paradoxical” given the party’s stance on the Israeli state, which it labeled an “discriminatory system” in a decision at its 2024 national meeting.

Approval of the Green party increased 9% among British Jews between the summer 2024 election and the following year, surpassing the 1% rise in Green support among the wider electorate over the equivalent interval, and coming before the guidance of a prominent member who identifies as a “proud” Jew but “not a Zionist”.

The analysis stated the increase in Green party support implied “for a significant minority of Jews, home affairs and liberal ideals take precedence over international affairs”.

At the same time, support for Reform rose among British Jews from 3% in August 2024 to 11% in June 2025. However the growth lagged the 14% jump the Reform Party received with the general public.

“Jews remain less inclined [than the general population] to vote for the Reform Party [11% vs 28%], but more inclined to support the Green Party [18% vs 7%],” the study stated.

A prominent expert said: “Reform is more inclined to draw men, older, traditional, and Zionist Jews; the Greens are more likely to draw younger, unaffiliated and non-Zionist …[but] it is crucial to acknowledge that it is also an element of a broader, broader shift driving the national electorate as a whole.”

However, the “surge in approval among the Jewish community for the Reform Party – a party whose discourse on immigration and nationalism would typically be anticipated to estrange diverse populations, like Jews” was called “notable” by analysts.

“Notable portions of the Jewish community may lean towards parties pledging firmness and direction, regardless of past associations” when traditional groups were viewed as “weak or hostile”, it added.

The analysis declared: “For the initial instance in modern British Jewish records, backing of the two main parties collectively has fallen below 60%.

“Given that this is mirrored in wider society too, it is not just a data outlier – it may signal a systemic transformation in Jewish political identity.

“Several factors are fueling this splintering: the Middle East hostilities and its polarising effect on Jewish opinions; growing anti-Jewish sentiment, peaking with a recent terrorist attack at a religious center; and a more general loss of confidence in mainstream parties.

“In combination, these issues are pushing Jews to political groups that offer direction – either via popular appeal or far-left ideals.

“If ongoing changes endure … the UK Jewish community are likely to become more politically polarised, prompting additional divisions within the community.”

The study group, which tracks population shifts, polled 11,000 Jewish residents of Britain for the analysis, titled The decline of dual-party dominance? Emerging changes in the electoral choices of the Jewish community.

It revealed that in 2024, the Jewish community were more prone than the wider public to back the two main parties, with 44% favoring the Labour Party, compared with 34% of the general public, and 32% backing Conservative, compared with 24% of the wider electorate.

By June, support for Labour had dropped by 13% among UK Jewish voters, versus a 9% decrease with the broader voter base, while backing for the Conservatives among the Jewish community fell by 4%, equaling the wider electorate. “Small and consistent” support for the Liberal Democrats has moved from 8% to 9% among British Jews.
