UK Jews Turning to Greens and Reform UK as Backing for Major Parties Declines

Findings show a new electoral split among British Jews, with approval increasing rapidly for the Green Party – driven by newer generation and “anti-Zionist” Jews – while more senior Orthodox men favor the Reform Party as trust in the leading parties “plummets”.

Approval of Labour and the Conservatives among UK Jewish voters had fallen to 58% by summer 2025 from nearly 84% in 2020, according to a study from a leading research institute, which stated it was “the lowest level we’ve documented by some distance”.

Labour is typically preferred by more “less observant” Jews while the Tories is historically favored by more “Orthodox” Jews.

In parallel, roughly 18% of UK Jewish voters (18%) were backing the Green Party by June 2025 – which analysts labeled “paradoxical” given its policy on the Israeli state, which it labeled an “apartheid state” in a vote at its 2024 party conference.

Support for the Green party increased 9% among UK Jewish voters between the summer 2024 election and the following year, exceeding the 1% rise in Green support among the broader voting population over the equivalent interval, and predating the leadership of a leading politician who identifies as a “committed” Jew but “not a Zionist”.

The report stated the growth in Green Party support indicated “for a significant minority of Jews, home affairs and forward-thinking principles take precedence over international affairs”.

Meanwhile, backing of Reform increased among UK Jewish voters from 3% in summer 2024 to 11% in the following year. However the rise trailed the 14% increase Reform UK received with the broader voter base.

“Jewish voters are less prone [than the general population] to support Reform [11% vs 28%], but more likely to back the Green party [18% vs 7%],” the analysis commented.

A prominent expert remarked: “The Reform Party is more likely to attract men, more senior, traditional, and Zionist Jews; the Green Party are more likely to appeal to newer generation, non-religious and anti-Israel …[but] it is essential to acknowledge that it is also a component of a wider, broader shift affecting the British public as a entirety.”

Nonetheless, the “rapid increase in Jewish support for Reform – a political group whose rhetoric on immigration and nationalism would typically be predicted to distance ethnic groups, including Jews” was labeled “notable” by analysts.

“Significant parts of the Jewish electorate may gravitate toward voices promising strength and direction, despite ideological baggage” when established parties were perceived as “indecisive or opposed”, it noted.

The report stated: “For the initial instance in contemporary UK Jewish records, approval of the two main parties together has fallen below 60%.

“Given that this is reflected in the broader public too, it is not just a data outlier – it may indicate a structural shift in the political views of Jews.

“Several factors are fueling this fragmentation: the war in Gaza and its polarising effect on Jewish attitudes; increasing hostility towards Jews, culminating in a notable violent incident at a religious center; and a more general loss of confidence in established parties.

“Collectively, these issues are pushing Jews in the direction of political groups that offer clarity – whether through popular appeal or far-left ideals.

“If recent developments persist … British Jews are predicted to become increasingly divided, leading to further internal community tensions.”

The research body, which monitors population shifts, polled 11,000 UK Jewish individuals for the analysis, called The end of two-party politics? New developments in the political preferences of the Jewish community.

It discovered that in the previous year, Jewish voters were more inclined than the general population to back the dominant groups, with 44% backing the Labour Party, compared with 34% of the electorate as a whole, and 32% supporting Conservative, against 24% of the broader public.

By summer, approval of Labour had declined by 13% among the Jewish community, against a 9% drop with the general public, while Conservative support among UK Jewish voters declined by 4%, matching the broader population. “Low and stable” backing of the Liberal Democrats has shifted from 8% to 9% among the Jewish community.
