British Jewish Community Shifting Towards Green Party and Reform Party as Backing for Main Parties Falls

Research has uncovered a new electoral split within the UK Jewish community, with approval increasing rapidly for the Greens – driven by newer generation and “anti-Zionist” Jews – while elderly traditional men lean toward Reform UK as confidence in the leading parties “collapses”.

Backing of the Conservative and Labour parties among the Jewish community in Britain had declined to 58% by July 2025 from around 84% in 2020, as per a analysis from a prominent research institute, which commented it was “the weakest support we’ve ever recorded by some distance”.

Generally, Labour has been preferred by more “secular” Jews while the Conservative party is traditionally backed by more “observant” Jews.

At the same time, nearly one in five Jewish individuals in Britain (18%) were backing the Green party by June 2025 – which researchers called “surprising” given the party’s stance on Israel, which it labeled an “segregationist regime” in a vote at its 2024 party conference.

Support for the Greens increased 9% among the Jewish community between the summer 2024 election and mid-2025, exceeding the 1% growth in backing for the Greens among the wider electorate over the same period, and preceding the guidance of a well-known member who identifies as a “committed” Jew but “not a Zionist”.

The study said the growth in Green Party support suggested “for a sizable segment of Jews, domestic priorities and progressive values outweigh international affairs”.

At the same time, approval of Reform UK grew among British Jews from 3% in August 2024 to 11% in June 2025. However the growth lagged the 14% increase Reform received with the wider electorate.

“Jewish voters are less inclined [than the wider electorate] to support Reform [11% vs 28%], but more inclined to support the Greens [18% vs 7%],” the report said.

A senior researcher noted: “Reform is more likely to attract men, elderly, orthodox, and Zionist Jews; the Green Party are more prone to attract newer generation, unaffiliated and non-Zionist …[but] it is important to note that it is also a component of a wider, wider pattern driving the British public as a entirety.”

Still, the “sharp rise in Jewish support for Reform UK – a party whose discourse on migration and patriotism would usually be anticipated to estrange minority communities, including Jews” was called “notable” by the study.

“Large segments of the Jewish electorate may gravitate toward leaders pledging resolve and certainty, despite past associations” when traditional groups were seen as “indecisive or hostile”, it noted.

The report stated: “For the first time in contemporary Jewish community records, support for the two main parties collectively has fallen below 60%.

“Given that this is reflected in the general population too, it is not just a numerical irregularity – it may suggest a systemic transformation in the political views of Jews.

“Several factors seem to be fueling this division: the war in Gaza and its divisive impact on Jewish opinions; increasing hostility towards Jews, peaking with a notable violent incident at a synagogue; and a more general loss of confidence in established parties.

“Collectively, these elements are driving Jews in the direction of organizations that deliver certainty – be it through populism or far-left ideals.

“If recent developments continue … Jewish voters in Britain are predicted to become increasingly divided, causing additional divisions within the community.”

The organization, which follows demographic trends, interviewed 11,000 UK Jewish individuals for the report, named The shift away from two-party support? Recent shifts in the electoral choices of British Jews.

It revealed that in the previous year, Jewish electors were more inclined than the broader electorate to vote for the leading parties, with 44% backing Labour, against 34% of the electorate as a whole, and 32% voting for Conservative, versus 24% of the wider electorate.

By mid-year, support for the Labour Party had slumped by 13% among UK Jewish voters, versus a 9% drop with the general public, while approval of the Tories among the Jewish community fell by 4%, matching the wider electorate. “Small and consistent” approval of the Lib Dems has moved from 8% to 9% among the Jewish community.
