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

Research has uncovered a new electoral split among Jewish people in Britain, with backing growing quickly for the Greens – driven by younger and non-Zionist Jews – while more senior observant men turn to the Reform Party as trust in the leading parties “drops sharply”.

Support for the Conservative and Labour parties among British Jews had declined to 58% by mid-2025 from nearly 84% in 2020, as per a study from a leading policy organization, which commented it was “the lowest level we’ve documented by a significant margin”.

Generally, Labour has been preferred by more “non-religious” Jews while the Tories is historically backed by more “observant” Jews.

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

Approval of the Green party increased 9% among the Jewish community between August 2024’s general election and mid-2025, outstripping the 1% increase in backing for the Greens among the wider electorate over the same period, and coming before the guidance of a well-known figure who describes himself as a “committed” Jew but “not a Zionist”.

The study noted the growth in Green party support suggested “for a notable portion of Jews, national issues and liberal ideals take precedence over international affairs”.

In contrast, approval of the Reform Party grew among British Jews from 3% in August 2024 to 11% in June 2025. However the increase lagged the 14% jump Reform UK enjoyed with the broader voter base.

“The community is less likely [than the wider electorate] to vote for Reform [11% vs 28%], but more inclined to vote for the Green Party [18% vs 7%],” the analysis said.

A lead analyst remarked: “Reform is more prone to draw men, elderly, orthodox, and pro-Israel Jews; the Greens are more prone to draw younger, secular and non-Zionist …[but] it is essential to acknowledge that it is also part of a wider, more general trend affecting the national electorate as a complete group.”

Still, the “sharp rise in Jewish support for the Reform Party – a organization whose rhetoric on border policy and national identity would typically be expected to alienate minority communities, like Jews” was called “notable” by the study.

“Notable portions of the Jewish community may lean towards voices pledging strength and certainty, despite political history” when mainstream parties were viewed as “weak or hostile”, it noted.

The analysis declared: “For the initial instance in contemporary British Jewish history, approval of the two main parties combined has declined to less than 60%.

“Given that this is seen in wider society too, it is not just a data outlier – it may indicate a systemic transformation in Jewish electoral behavior.

“Three forces appear to be driving this fragmentation: the Gaza conflict and its polarising effect on Jewish attitudes; rising antisemitism, culminating in a recent security breach at a religious center; and a wider loss of confidence in traditional political groups.

“In combination, these factors are pushing Jews to organizations that offer clarity – be it through popular appeal or radical progressivism.

“If recent developments continue … the UK Jewish community are predicted to become more politically polarised, leading to additional strain among Jewish groups.”

The study group, which follows demographic trends, polled 11,000 British Jews for the analysis, called The decline of dual-party dominance? New developments in the political preferences of the Jewish community.

It discovered that in the previous year, Jewish electors were more prone than the broader electorate to support the two main parties, with 44% supporting Labour, versus 34% of the total voters, and 32% supporting the Conservative Party, versus 24% of the wider electorate.

By mid-year, approval of the Labour Party had slumped by 13% among British Jews, versus a 9% decrease with the wider electorate, while backing for the Conservatives among the Jewish community fell by 4%, equaling the broader population. “Minimal and steady” approval of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
