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

Research has uncovered a fresh political divide among British Jews, with backing growing quickly for the Greens – propelled by younger and “anti-Zionist” Jews – while older Orthodox men turn to Reform UK as faith in the two main parties “drops sharply”.

Backing of the Conservative and Labour parties among the Jewish community in Britain had declined to 58% by summer 2025 from around 84% in 2020, as per a report from a respected demographic center, which noted it was “the weakest support we’ve documented by a significant margin”.

Generally, Labour has been favored by more “secular” Jews while the Tories is historically backed by more “observant” Jews.

Meanwhile, roughly a fifth of British Jews (18%) were backing the Greens by summer 2025 – which researchers labeled “paradoxical” given its position on Israel, which it termed an “apartheid state” in a decision at its 2024 party conference.

Backing of the Green Party rose 9% among British Jews between the summer 2024 election and the following year, exceeding the 1% growth in approval of the Green Party among the general public over the identical timeframe, and predating the guidance of a well-known politician who describes himself as a “proud” Jew but “not a Zionist”.

The analysis said the growth in Greens support implied “for a sizable segment of Jews, domestic priorities and forward-thinking principles take precedence over international affairs”.

In contrast, approval of the Reform Party rose among UK Jewish voters from 3% in August 2024 to 11% in mid-2025. However the growth lagged the 14% increase Reform UK experienced with the wider electorate.

“The community is less likely [than the broader public] to back the Reform Party [11% vs 28%], but more likely to support the Green Party [18% vs 7%],” the analysis said.

A senior researcher remarked: “The Reform Party is more prone to appeal to male, elderly, traditional, and Zionist Jews; the Green Party are more prone to draw youthful, unaffiliated and anti-Zionist …[but] it is important to recognize that it is also a component of a larger, wider pattern driving the British public as a complete group.”

Still, the “rapid increase in approval among the Jewish community for Reform UK – a organization whose language on migration and nationalism would normally be expected to estrange minority communities, including Jews” was described as “striking” by analysts.

“Notable portions of the Jewish electorate may lean towards parties offering resolve and clarity, despite ideological baggage” when traditional groups were seen as “ineffective or hostile”, it noted.

The report said: “For the initial instance in contemporary UK Jewish experience, backing 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 data outlier – it may signal a fundamental change in Jewish electoral behavior.

“Several factors appear to be driving this splintering: the Gaza conflict and its splitting influence on Jewish attitudes; growing anti-Jewish sentiment, resulting in a major violent incident at a synagogue; and a more general loss of confidence in traditional political groups.

“Collectively, these elements are driving Jews toward organizations that offer clarity – either via populism or far-left ideals.

“If current trends persist … Jewish voters in Britain are likely to become increasingly divided, leading to further internal community tensions.”

The organization, which follows population shifts, polled 11,000 UK Jewish individuals for the analysis, named The decline of dual-party dominance? New developments in the electoral choices of British Jews.

It revealed that in the previous year, the Jewish community were more inclined than the wider public to support the leading parties, with 44% favoring Labour, versus 34% of the general public, and 32% voting for the Conservative Party, versus 24% of the general population.

By summer, support for Labour had slumped by 13% among British Jews, against a 9% decrease with the general public, while approval of the Tories among the Jewish community dropped by 4%, equaling the broader population. “Minimal and steady” approval of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
