British Jewish Community Turning to Green Party and Reform UK as Support for Main Parties Declines

Findings show a emerging political divide within Jewish people in Britain, with backing increasing rapidly for the Green Party – driven by younger and “anti-Zionist” Jews – while elderly traditional men favor Reform UK as trust in the two main parties “plummets”.

Backing of the Conservative and Labour parties among UK Jewish voters had declined to 58% by July 2025 from around 84% in 2020, based on a report from a leading policy organization, which stated it was “the lowest level we’ve documented by some distance”.

Labour is typically preferred by more “non-religious” Jews while the Conservative party is historically backed by more “religious” Jews.

Meanwhile, almost one in five UK Jewish voters (18%) were favoring the Green party by June 2025 – which analysts described as “contradictory” given its position on Israel, which it described an “discriminatory system” in a decision at its 2024 national meeting.

Support for the Green party increased 9% among British Jews between August 2024’s general election and June 2025, exceeding the 1% growth in backing for the Greens among the broader voting population over the same period, and preceding the leadership of a prominent member who identifies as a “devout” Jew but “anti-Zionist”.

The analysis said the growth in Green Party support indicated “for a sizable segment of Jews, home affairs and forward-thinking principles outweigh international affairs”.

At the same time, backing of Reform rose among UK Jewish voters from 3% in August 2024 to 11% in mid-2025. However the rise fell behind the 14% rise the Reform Party enjoyed with the general public.

“Jewish voters are less prone [than the general population] to support Reform UK [11% vs 28%], but more inclined to support the Green party [18% vs 7%],” the report said.

A prominent expert noted: “Reform is more prone to draw male, more senior, orthodox, and pro-Israel Jews; the Greens are more likely to appeal to newer generation, unaffiliated and anti-Zionist …[but] it is essential to note that it is also part of a broader, broader shift affecting the national electorate as a whole.”

Still, the “rapid increase in approval among the Jewish community for Reform – a political group whose discourse on border policy and patriotism would typically be anticipated to estrange ethnic groups, including Jews” was described as “striking” by researchers.

“Large segments of the Jewish population may move toward parties promising resolve and certainty, despite political history” when mainstream parties were perceived as “indecisive or opposed”, it added.

The report stated: “For the earliest occasion in modern Jewish community records, support for the Conservative and Labour parties together has dropped under 60%.

“Given that this is seen in the general population too, it is not just a numerical irregularity – it may indicate a structural shift in Jewish electoral behavior.

“Several factors are driving this division: the war in Gaza and its splitting influence on Jewish opinions; growing anti-Jewish sentiment, peaking with a recent security breach at a Jewish house of worship; and a broader collapse of trust in established parties.

“Collectively, these issues are pushing Jews to parties that offer certainty – whether through populism or extreme liberalism.

“If current trends persist … the UK Jewish community are expected to become further split, prompting more strain among Jewish groups.”

The organization, which tracks community changes, interviewed 11,000 British Jews for the report, named The decline of dual-party dominance? New developments in the political preferences of UK Jewish voters.

It found that in 2024, the Jewish community were more likely than the wider public to back the two main parties, with 44% supporting the Labour Party, against 34% of the total voters, and 32% backing the Conservative Party, against 24% of the general population.

By June, backing of Labour had slumped by 13% among British Jews, versus a 9% decline with the wider electorate, while approval of the Tories among the Jewish community declined by 4%, paralleling the general public. “Minimal and steady” backing of the Liberal Democrats has moved from 8% to 9% among UK Jewish voters.
