British Jews Turning to Greens and Reform UK as Support for Major Parties Declines
Research has uncovered a new political divide across Jewish people in Britain, with support rising fast for the Greens – driven by youthful and anti-Israel Jews – while older observant men lean toward Reform UK as confidence in the two main parties “drops sharply”.
Backing of Labour and the Conservatives among British Jews had fallen to 58% by mid-2025 from around 84% in 2020, according to a report from a leading research institute, which commented it was “the smallest share we’ve observed by some distance”.
Traditionally, Labour is supported by more “non-religious” Jews while the Conservatives is conventionally backed by more “observant” Jews.
At the same time, roughly 18% of British Jews (18%) were favoring the Green party by summer 2025 – which analysts called “surprising” given the party’s stance on Israel, which it described an “segregationist regime” in a vote at its 2024 party conference.
Support for the Green Party increased 9% among UK Jewish voters between the 2024 general election and June 2025, outstripping the 1% rise in approval of the Green Party among the broader voting population over the same period, and preceding the direction of a leading figure who describes himself as a “devout” Jew but “anti-Zionist”.
The analysis stated the increase in Green party support implied “for a significant minority of Jews, domestic priorities and forward-thinking principles take precedence over foreign policy concerns”.
At the same time, backing of Reform grew among UK Jewish voters from 3% in summer 2024 to 11% in June 2025. But the rise trailed the 14% increase Reform UK enjoyed with the broader voter base.
“The community is less inclined [than the broader public] to support the Reform Party [11% vs 28%], but more likely to support the Greens [18% vs 7%],” the report stated.
A lead analyst noted: “The Reform Party is more likely to appeal to male, elderly, traditional, and pro-Israel Jews; the Green Party are more likely to attract younger, non-religious and anti-Zionist …[but] it is essential to acknowledge that it is also a component of a wider, broader shift influencing the national electorate as a entirety.”
Nonetheless, the “rapid increase in approval among the Jewish community for Reform UK – a political group whose language on immigration and nationalism would typically be expected to estrange diverse populations, like Jews” was called “notable” by analysts.
“Notable portions of the Jewish electorate may move toward parties offering resolve and certainty, regardless of political history” when established parties were seen as “ineffective or hostile”, it noted.
The report stated: “For the initial instance in recent UK Jewish history, backing of the Conservative and Labour parties together has dropped under 60%.
“Given that this is reflected in the broader public too, it is not just a statistical anomaly – it may indicate a systemic transformation in Jewish electoral behavior.
“Multiple drivers seem to be fueling this splintering: the Middle East hostilities and its splitting influence on community views; growing anti-Jewish sentiment, peaking with a recent terrorist attack at a synagogue; and a broader loss of confidence in mainstream parties.
“In combination, these issues are pushing Jews toward organizations that provide direction – whether through popular appeal or far-left ideals.
“If ongoing changes endure … the UK Jewish community are likely to become more politically polarised, leading to additional internal community tensions.”
The study group, which follows demographic trends, surveyed 11,000 British Jews for the analysis, titled The end of two-party politics? Emerging changes in the electoral choices of UK Jewish voters.
It revealed that in the election year, Jewish electors were more prone than the wider public to back the leading parties, with 44% backing Labour, versus 34% of the general public, and 32% supporting Conservative, versus 24% of the wider electorate.
By mid-year, approval of Labour had dropped by 13% among British Jews, against a 9% drop with the general public, while Conservative support among British Jews dropped by 4%, paralleling the general public. “Small and consistent” backing of the Liberal Democrats has shifted from 8% to 9% among the Jewish community.
