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

Findings show a new electoral split among the UK Jewish community, with approval increasing rapidly for the Greens – propelled by newer generation and non-Zionist Jews – while older Orthodox men lean toward Reform UK as faith in the dominant political groups “collapses”.

Backing of the two major UK parties among British Jews had declined to 58% by mid-2025 from almost 84% in 2020, as per a analysis from a leading policy organization, which noted it was “the smallest share we’ve observed by some distance”.

Labour is typically favored by more “less observant” Jews while the Tories is historically favored by more “religious” Jews.

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

Backing of the Green party rose 9% among the Jewish community between the 2024 general election and June 2025, surpassing the 1% growth in Green support among the broader voting population over the identical timeframe, and preceding the direction of a leading member who describes himself as a “committed” Jew but “non-Zionist”.

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

In contrast, approval of Reform grew among British Jews from 3% in the 2024 election to 11% in June 2025. Yet the rise trailed the 14% increase Reform UK experienced with the general public.

“The community is less prone [than the general population] to support Reform UK [11% vs 28%], but more inclined to vote for the Green Party [18% vs 7%],” the analysis said.

A senior researcher remarked: “Reform is more prone to appeal to male, older, orthodox, and pro-Israel Jews; the Green Party are more prone to appeal to newer generation, unaffiliated and non-Zionist …[but] it is essential to note that it is also a component of a broader, broader shift influencing the UK population as a entirety.”

However, the “sharp rise in approval among the Jewish community for Reform UK – a organization whose discourse on immigration and patriotism would normally be predicted to alienate diverse populations, such as Jews” was labeled “striking” by researchers.

“Large segments of the Jewish community may lean towards leaders pledging firmness and direction, regardless of ideological baggage” when established parties were seen as “weak or opposed”, it commented.

The analysis said: “For the earliest occasion in recent British Jewish records, support for the Conservative and Labour parties combined has dropped under 60%.

“Given that this is mirrored in wider society too, it is not just a data outlier – it may indicate a structural shift in Jewish electoral behavior.

“Several factors are propelling this splintering: the Gaza conflict and its splitting influence on Jewish opinions; rising antisemitism, resulting in a recent security breach at a synagogue; and a wider erosion of faith in established parties.

“Together, these issues are pushing Jews toward political groups that provide certainty – either via popular appeal or extreme liberalism.

“If ongoing changes continue … the UK Jewish community are expected to become increasingly divided, leading to further internal community tensions.”

The organization, which tracks demographic trends, surveyed 11,000 Jewish residents of Britain for the study, titled The end of two-party politics? New developments in the voting patterns of the Jewish community.

It discovered that in the previous year, Jewish voters were more inclined than the general population to back the two main parties, with 44% favoring Labour, against 34% of the general public, and 32% backing Conservative, against 24% of the general population.

By summer, backing of the Labour Party had declined by 13% among British Jews, versus a 9% drop with the wider electorate, while Conservative support among British Jews fell by 4%, equaling the wider electorate. “Small and consistent” backing of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
