British Jews Gravitating to Green Party and Reform Party as Backing for Major Parties Declines

Studies reveal a fresh electoral split among the UK Jewish community, with approval increasing rapidly for the Green Party – driven by younger and “anti-Zionist” Jews – while older traditional men favor Reform UK as confidence in the two main parties “collapses”.

Backing of the two major UK parties among British Jews had dropped to 58% by summer 2025 from almost 84% in 2020, as per a report from a prominent demographic center, which stated it was “the smallest share we’ve ever recorded by a significant margin”.

Traditionally, Labour is favored by more “less observant” Jews while the Conservatives is traditionally preferred by more “observant” Jews.

In parallel, roughly 18% of Jewish individuals in Britain (18%) were favoring the Green Party by June 2025 – which the study labeled “contradictory” given its policy on Israel, which it labeled an “apartheid state” in a resolution at its 2024 Manchester conference.

Support for the Greens rose 9% among UK Jewish voters between August 2024’s general election and the following year, exceeding the 1% increase in Green support among the wider electorate over the same period, and predating the guidance of a well-known figure who identifies as a “devout” Jew but “not a Zionist”.

The report noted the growth in Green party support indicated “for a significant minority of Jews, domestic priorities and progressive values outweigh foreign policy concerns”.

Meanwhile, backing of Reform rose among the Jewish community from 3% in summer 2024 to 11% in mid-2025. However the growth lagged the 14% rise Reform UK enjoyed with the general public.

“The community is less likely [than the general population] to vote for the Reform Party [11% vs 28%], but more likely to vote for the Green party [18% vs 7%],” the report said.

A lead analyst said: “Reform is more likely to appeal to men, older, traditional, and pro-Israel Jews; the Greens are more likely to draw younger, secular and anti-Zionist …[but] it is essential to acknowledge that it is also an element of a larger, more general trend influencing the national electorate as a whole.”

Still, the “rapid increase in Jewish support for Reform – a organization whose language on immigration and nationalism would usually be predicted to alienate ethnic groups, like Jews” was called “striking” by researchers.

“Large segments of the Jewish electorate may lean towards voices offering resolve and direction, despite political history” when mainstream parties were seen as “indecisive or unfriendly”, it added.

The report stated: “For the earliest occasion in modern Jewish community history, support for the Conservative and Labour parties together has declined to less than 60%.

“Given that this is reflected in wider society too, it is not just a data outlier – it may suggest a systemic transformation in the political views of Jews.

“Multiple drivers seem to be propelling this splintering: the Middle East hostilities and its divisive impact on community views; increasing hostility towards Jews, resulting in a major security breach at a Jewish house of worship; and a wider erosion of faith in established parties.

“Collectively, these issues are driving Jews to parties that provide direction – either via popular appeal or extreme liberalism.

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

The organization, which tracks demographic trends, polled 11,000 Jewish residents of Britain for the analysis, called The decline of dual-party dominance? Emerging changes in the political preferences of British Jews.

It revealed that in 2024, Jewish voters were more prone than the broader electorate to support the dominant groups, with 44% backing the Labour Party, compared with 34% of the total voters, and 32% voting for Conservative, against 24% of the broader public.

By summer, backing of the Labour Party had dropped by 13% among the Jewish community, versus a 9% drop with the wider electorate, while backing for the Conservatives among British Jews dropped by 4%, paralleling the broader population. “Low and stable” backing of the Liberal Democrats has changed from 8% to 9% among British Jews.
