UK Jewish Community Shifting Towards Green Party and Reform Party as Backing for Major Parties Falls

Research has uncovered a fresh political divide within British Jews, with backing growing quickly for the Greens – buoyed up by newer generation and “anti-Zionist” Jews – while elderly observant men lean toward the Reform Party as faith in the leading parties “plummets”.

Backing of Labour and the Conservatives among UK Jewish voters had declined to 58% by July 2025 from around 84% in 2020, according to a study from a leading research institute, which commented it was “the weakest support we’ve documented by a wide gap”.

Traditionally, Labour is supported by more “non-religious” Jews while the Conservatives is conventionally preferred by more “observant” Jews.

In parallel, nearly 18% of UK Jewish voters (18%) were favoring the Green party by summer 2025 – which analysts described as “contradictory” given the party’s stance on Israel, which it described an “apartheid state” in a vote at its 2024 Manchester conference.

Approval of the Green Party increased 9% among UK Jewish voters between the summer 2024 election and mid-2025, surpassing the 1% rise in approval of the Green Party among the general public over the identical timeframe, and predating the leadership of a leading member who describes himself as a “devout” Jew but “non-Zionist”.

The report stated the rise in Green party support implied “for a significant minority of Jews, domestic priorities and liberal ideals outweigh international affairs”.

Meanwhile, support for the Reform Party grew among British Jews from 3% in August 2024 to 11% in mid-2025. However the growth fell behind the 14% jump Reform UK enjoyed with the broader voter base.

“Jews remain less inclined [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 study stated.

A prominent expert remarked: “The Reform Party is more prone to draw men, more senior, observant, and pro-Israel Jews; the Greens are more likely to draw younger, unaffiliated and anti-Zionist …[but] it is important to note that it is also a component of a wider, wider pattern driving the UK population as a whole.”

Nonetheless, the “rapid increase in Jewish support for Reform UK – a party whose discourse on border policy and nationalism would usually be predicted to estrange minority communities, including Jews” was called “striking” by analysts.

“Notable portions of the Jewish population may gravitate toward voices offering strength and clarity, irrespective of past associations” when mainstream parties were viewed as “ineffective or opposed”, it added.

The analysis said: “For the first time in modern Jewish community history, approval of the two main parties together has declined to less than 60%.

“Given that this is seen in wider society too, it is not just a numerical irregularity – it may signal a structural shift in Jewish political identity.

“Multiple drivers appear to be fueling this fragmentation: the Gaza conflict and its splitting influence on community views; rising antisemitism, culminating in a notable security breach at a synagogue; and a wider collapse of trust in traditional political groups.

“Collectively, these factors are guiding Jews toward political groups that offer clarity – whether through mass rhetoric or extreme liberalism.

“If recent developments continue … British Jews are expected to become further split, causing more divisions within the community.”

The research body, which follows community changes, surveyed 11,000 British Jews for the study, titled The decline of dual-party dominance? Recent shifts in the electoral choices of British Jews.

It discovered that in the previous year, Jewish electors were more inclined than the general population to vote for the two main parties, with 44% backing Labour, against 34% of the electorate as a whole, and 32% backing the Conservative Party, compared with 24% of the wider electorate.

By June, approval of the Labour Party had slumped by 13% among the Jewish community, against a 9% decrease with the general public, while approval of the Tories among British Jews fell by 4%, equaling the broader population. “Minimal and steady” backing of the Liberal Democrats has changed from 8% to 9% among UK Jewish voters.
