British Jews Gravitating to Greens and Reform UK as Backing for Major Parties Drops

Research has uncovered a fresh party division across Jewish people in Britain, with support growing quickly for the Green Party – propelled by younger and anti-Israel Jews – while elderly traditional men turn to Reform UK as trust in the leading parties “plummets”.

Support for the two major UK parties among the Jewish community in Britain had declined to 58% by summer 2025 from nearly 84% in 2020, according to a study from a leading demographic center, which noted it was “the lowest level we’ve documented by a wide gap”.

Traditionally, Labour is favored by more “less observant” Jews while the Conservatives is historically preferred by more “Orthodox” Jews.

Meanwhile, roughly one in five UK Jewish voters (18%) were supporting the Green Party by mid-2025 – which researchers called “surprising” given its policy on Israel, which it labeled an “discriminatory system” in a vote at its 2024 Manchester conference.

Approval of the Greens grew 9% among UK Jewish voters between August 2024’s general election and the following year, exceeding the 1% increase in backing for the Greens among the general public over the equivalent interval, and preceding the direction of a well-known member who states he is a “committed” Jew but “not a Zionist”.

The report noted the growth in Green Party support suggested “for a notable portion of Jews, domestic priorities and liberal ideals take precedence over international affairs”.

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

“Jews remain less prone [than the wider electorate] to vote for Reform [11% vs 28%], but more likely to back the Green Party [18% vs 7%],” the report commented.

A lead analyst said: “The Reform Party is more inclined to appeal to male, more senior, traditional, and Zionist Jews; the Green Party are more likely to draw newer generation, non-religious and anti-Israel …[but] it is crucial to recognize that it is also an element of a larger, wider pattern driving the British public as a whole.”

Nonetheless, the “rapid increase in approval among the Jewish community for the Reform Party – a political group whose discourse on migration and patriotism would normally be predicted to alienate ethnic groups, including Jews” was labeled “notable” by the study.

“Notable portions of the Jewish community may move toward parties pledging resolve and direction, despite political history” when mainstream parties were viewed as “ineffective or unfriendly”, it added.

The report stated: “For the first time in recent Jewish community records, backing of the two main parties together has fallen below 60%.

“Given that this is mirrored in wider society too, it is not just a statistical anomaly – it may suggest a systemic transformation in Jewish political identity.

“Three forces seem to be fueling this splintering: the Middle East hostilities and its divisive impact on Jewish opinions; rising antisemitism, culminating in a notable terrorist attack at a religious center; and a more general erosion of faith in established parties.

“Together, these factors are guiding Jews in the direction of parties that offer certainty – either via populism or far-left ideals.

“If current trends endure … Jewish voters in Britain are predicted to become more politically polarised, leading to further strain among Jewish groups.”

The study group, which tracks community changes, polled 11,000 Jewish residents of Britain for the report, titled The decline of dual-party dominance? Recent shifts in the political preferences of the Jewish community.

It discovered that in 2024, Jewish voters were more prone than the broader electorate to back the leading parties, with 44% backing Labour, against 34% of the total voters, and 32% voting for the Conservative Party, compared with 24% of the wider electorate.

By mid-year, backing of the Labour Party had declined by 13% among UK Jewish voters, compared with a 9% decrease with the wider electorate, while backing for the Conservatives among UK Jewish voters fell by 4%, equaling the general public. “Low and stable” support for the Lib Dems has moved from 8% to 9% among the Jewish community.
