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

Findings show a fresh electoral split among British Jews, with approval increasing rapidly for the Green Party – propelled by newer generation and anti-Israel Jews – while more senior traditional men favor the Reform Party as confidence in the two main parties “collapses”.

Backing of the two major UK parties among British Jews had dropped to 58% by summer 2025 from almost 84% in 2020, as per a analysis from a respected research institute, which stated it was “the smallest share we’ve documented by a significant margin”.

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

Meanwhile, nearly a fifth of UK Jewish voters (18%) were supporting the Greens by mid-2025 – which the study labeled “paradoxical” given its policy on the Israeli state, which it termed an “discriminatory system” in a vote at its 2024 party conference.

Backing of the Green Party grew 9% among British Jews between the summer 2024 election and June 2025, outstripping the 1% growth in backing for the Greens among the wider electorate over the equivalent interval, and predating the leadership of a prominent figure who states he is a “committed” Jew but “non-Zionist”.

The study noted the growth in Greens support implied “for a significant minority of Jews, domestic priorities and liberal ideals take precedence over foreign policy concerns”.

At the same time, backing of Reform UK grew among UK Jewish voters from 3% in the 2024 election to 11% in the following year. Yet the growth lagged the 14% rise Reform experienced with the broader voter base.

“Jewish voters are less prone [than the broader public] to support the Reform Party [11% vs 28%], but more prone to back the Green Party [18% vs 7%],” the study commented.

A lead analyst remarked: “Reform is more inclined to draw male, elderly, traditional, and pro-Israel Jews; the Green Party are more inclined to attract younger, non-religious and anti-Israel …[but] it is crucial to acknowledge that it is also a component of a broader, wider pattern influencing the national electorate as a whole.”

However, the “surge in approval among the Jewish community for the Reform Party – a political group whose rhetoric on migration and patriotism would typically be anticipated to estrange diverse populations, like Jews” was labeled “striking” by the study.

“Notable portions of the Jewish community may gravitate toward voices promising strength and direction, despite political history” when traditional groups were viewed as “indecisive or unfriendly”, it noted.

The study stated: “For the initial instance in modern Jewish community history, support for the Labour and Conservative parties combined has fallen below 60%.

“Given that this is seen in wider society too, it is not just a numerical irregularity – it may indicate a fundamental change in Jewish electoral behavior.

“Several factors appear to be propelling this division: the Middle East hostilities and its splitting influence on community views; increasing hostility towards Jews, peaking with a recent violent incident at a Jewish house of worship; and a wider erosion of faith in mainstream parties.

“Collectively, these factors are guiding Jews to political groups that offer certainty – be it through mass rhetoric or extreme liberalism.

“If ongoing changes persist … British Jews are likely to become more politically polarised, leading to more internal community tensions.”

The research body, which monitors population shifts, interviewed 11,000 British Jews for the study, called The shift away from two-party support? Emerging changes in the voting patterns of UK Jewish voters.

It found that in the previous year, the Jewish community were more likely than the general population to vote for the dominant groups, with 44% favoring Labour, versus 34% of the general public, and 32% supporting Conservative, against 24% of the broader public.

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