UK Jews Shifting Towards Green Party and Reform Party as Support for Main Parties Declines

Research has uncovered a fresh party division among Jewish people in Britain, with support increasing rapidly for the Greens – buoyed up by younger and “anti-Zionist” Jews – while elderly traditional men lean toward Reform UK as trust in the dominant political groups “plummets”.

Backing of Labour and the Conservatives among UK Jewish voters had declined to 58% by mid-2025 from nearly 84% in 2020, as per a study from a prominent policy organization, which stated it was “the smallest share we’ve observed by a wide gap”.

Generally, Labour has been supported by more “less observant” Jews while the Conservative party is historically backed by more “observant” Jews.

In parallel, nearly one in five Jewish individuals in Britain (18%) were favoring the Green party by mid-2025 – which the study labeled “contradictory” given the party’s stance on the Israeli state, which it labeled an “segregationist regime” in a decision at its 2024 Manchester conference.

Support for the Green party grew 9% among the Jewish community between the 2024 general election and mid-2025, exceeding the 1% growth in approval of the Green Party among the general public over the same period, and predating the leadership of a well-known politician who identifies as a “committed” Jew but “non-Zionist”.

The study noted the rise in Green Party support implied “for a notable portion of Jews, domestic priorities and forward-thinking principles outweigh global matters”.

In contrast, support for the Reform Party grew among UK Jewish voters from 3% in summer 2024 to 11% in June 2025. But the rise lagged the 14% increase Reform experienced with the general public.

“The community is less prone [than the broader public] to vote for Reform [11% vs 28%], but more likely to back the Green party [18% vs 7%],” the report commented.

A senior researcher said: “The Reform Party is more inclined to appeal to male, older, traditional, and pro-Israel Jews; the Greens are more likely to draw youthful, non-religious and anti-Israel …[but] it is important to acknowledge that it is also an element of a larger, more general trend driving the national electorate as a complete group.”

However, the “rapid increase in backing from Jews for the Reform Party – a party whose rhetoric on migration and patriotism would usually be anticipated to alienate minority communities, such as Jews” was called “striking” by the study.

“Notable portions of the Jewish population may lean towards leaders pledging firmness and direction, despite ideological baggage” when established parties were perceived as “indecisive or unfriendly”, it commented.

The analysis said: “For the earliest occasion in recent Jewish community experience, support for the two main parties collectively has declined to less than 60%.

“Given that this is reflected in wider society too, it is not just a data outlier – it may indicate a fundamental change in Jewish political identity.

“Three forces appear to be driving this fragmentation: the Middle East hostilities and its divisive impact on Jewish attitudes; rising antisemitism, peaking with a recent terrorist attack at a Jewish house of worship; and a broader collapse of trust in established parties.

“In combination, these elements are guiding Jews in the direction of political groups that offer certainty – either via popular appeal or far-left ideals.

“If ongoing changes endure … British Jews are likely to become increasingly divided, causing additional internal community tensions.”

The research body, which tracks demographic trends, interviewed 11,000 UK Jewish individuals for the report, titled The shift away from two-party support? Emerging changes in the political preferences of the Jewish community.

It found that in the election year, the Jewish community were more likely than the general population to support the dominant groups, with 44% backing the Labour Party, against 34% of the total voters, and 32% backing the Conservative Party, against 24% of the broader public.

By summer, support for Labour had slumped by 13% among UK Jewish voters, compared with a 9% decrease with the broader voter base, while approval of the Tories among British Jews fell by 4%, matching the general public. “Minimal and steady” backing of the Lib Dems has shifted from 8% to 9% among the Jewish community.
