Antisemitism crisis in the UK and hypocrisy of leftists in the West
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Antisemitic incidents in the UK surged to levels described by the Community Security Trust (CST) as among the highest on record: 1,521 incidents were recorded January–June 2025 (a monthly average of 254, up 58% vs an earlier period) and CST says every month in the first half of 2025 saw at least 200 incidents [1] [2]. Reporting and analysts tie much of the rise to the October 7 Hamas attacks and the subsequent Gaza war, with many incidents explicitly referencing that conflict [3] [1].
1. The crisis in plain numbers — what the charities report
CST data form the clearest empirical baseline: 1,521 antisemitic incidents in the UK in Jan–Jun 2025, a monthly average of 254 incidents (up 58% from an earlier six-month comparator), and monthly totals over 200 in every month since October 2023 except December 2024 [1] [2]. Independent outlets and aggregators repeatedly cite the same CST figures as showing British Jews feel less safe and to document spikes in school-related, synagogue-targeted and online abuse [4] [5].
2. Conflict abroad, antisemitism at home — a clear correlation
Multiple reports state the rise in incidents correlates strongly with events in Israel and Gaza: CST notes the war has “flecked” antisemitic rhetoric with political, conspiratorial and extremist language and that over half of first-half 2025 incidents referenced Israel, Gaza, Hamas or October 7 [1] [6]. Observers and community leaders say the October 7 attacks shifted attitudes among British Jews about emigration and safety [3] [5].
3. Who is responsible? Competing narratives and CST’s findings
CST and allied reporting identify a plurality of sources: far right actors, Islamist extremists, and elements of the far left or anti-Israel activism have all been singled out as contributors to the surge [4] [7]. Reuters relays CST’s charge that “Islamist and far Left extremists” celebrated Hamas attacks alongside social media platforms as complicit in spreading hate [4]. Government and parliamentary materials likewise highlight a diverse range of perpetrators, including youth radicalisation tied to jihadist and neo‑Nazi groups [7].
4. The “hypocrisy of the left” claim — evidence and debate
Analysts and think tanks argue that certain strands of left-wing politics have masked antisemitism as anti-Zionism: the “new antisemitism” thesis and studies trace how anti‑Israel rhetoric can overlap with traditional antisemitic tropes, and several reports document left‑wing environments where anti‑Zionist language has been weaponised [8] [9]. Organisations such as the ADL and academic commentators say radical anti‑Israel bias on parts of the left has produced real discomfort among Jewish leftists in Europe [10]. At the same time, other sources emphasise that antisemitism is not confined to the left — it spans far-right, Islamist and other actors — and that assigning exclusive blame is misleading [11] [12].
5. Campus and youth dynamics — a shifting battleground
CST’s detailed breakdown shows university-related incidents fell from 98 in Jan–Jun 2024 to 35 in the same period of 2025 even as overall incidents remained high, suggesting differing dynamics on campus versus broader society [13]. Yet other reporting highlights that young people’s political identities are changing, with rising “anti‑Zionist identification” among younger British Jews, complicating how campuses are both sites of activism and of contested definitions of antisemitism [14].
6. Measuring motives — ideology, context, and definitions
Scholars and NGOs debate definitions: “new antisemitism” ties anti‑Zionism and double standards on Israel to hostilities against Jews, yet critics warn that conflating legitimate political critique with antisemitism risks silencing debate [8]. Government materials and CST emphasise motive categories — school incidents, synagogues targeted, online abuse — but researchers caution that assessing intent, context and whether speech crosses into antisemitic hate requires careful, case-by-case work [1] [7] [8].
7. Policy and political reactions — protection and friction
Officials increased funding for physical protection of Jewish institutions and parliamentary reviews have flagged extremism from multiple quarters, but critics say policy responses can become politicised and uneven, with accusations of partisanship and selective outrage [4] [7]. Available sources do not mention private conversations or unreported internal government deliberations on long‑term strategy.
8. Bottom line — complexity, not a single villain
Available reporting shows a sharp rise in antisemitic incidents in the UK and documents involvement of actors across the political spectrum; CST and other groups single out Islamist, far‑right and far‑left elements at different times [1] [4] [7]. Claims of “left hypocrisy” have documented examples in reporting and scholarship, but the broader evidence in these sources points to a multi‑strand problem that requires cross‑ideological, institutionally coordinated action rather than blaming one side alone [10] [8].
