A new political divide is emerging among British Jews, with support for the Labour and Conservative parties plummeting to a historic low, according to research from the Institute of Jewish Policy Research (JPR). The proportion of Jewish voters backing the two main parties fell from nearly 84% in 2020 to just 58% by July 2025, the lowest level ever recorded by the institute.
The Greens have seen a surge in support, particularly among younger and anti-Zionist Jews, rising to 18% by June 2025. This is up 9% since the 2024 general election, far outpacing the 1% increase among the wider electorate. The JPR described the shift as paradoxical given the party's stance on Israel, which it labelled an apartheid state in 2024.
Reform UK has also gained traction, drawing older, Orthodox, and Zionist Jews. Backing for the party rose from 3% in August 2024 to 11% in June 2025, though this lagged the 14% rise seen among the general public. The JPR noted that Reform's nationalist rhetoric would typically alienate minority communities, making the surge striking.
Dr Jonathan Boyd, JPR's executive director, said the Greens are attracting younger, unaffiliated, and anti-Zionist Jews, while Reform UK appeals to male, older, Orthodox, and Zionist Jews. He added that the fragmentation reflects a broader trend in the UK population, but is amplified by the war in Gaza, rising antisemitism, and a collapse of trust in mainstream parties.
The JPR surveyed 11,000 British Jews for the report, titled 'The end of two-party politics?', and warned that the polarisation could heighten internal community tensions if current trends persist.
