Antisemitic incidents have surged across the United Kingdom in the wake of the October 7 terrorist attack on Israel and the ongoing conflict in Gaza, prompting concern among community leaders and officials. The increase in hostile rhetoric and actions has manifested in public demonstrations, social media activity, and local government decisions, underscoring a broader challenge in addressing growing intolerance.

In London, repeated marches through central areas have frequently included expressions of anti-Jewish and anti-Israel sentiment, while social media platforms have become significant arenas for the spread of hateful language. Critics have pointed to the failure of major technology companies to curb such content, with antisemitic attacks often starting with hostile online discourse, according to Marina Rosenberg, a co-author of a recent report on the issue.

An illustrative development occurred in the London borough of Hackney, where the local council, led by the Green Party, voted to end its longstanding twinning arrangement with the Israeli city of Haifa. The council set an October 7 deadline for Haifa’s response, coinciding with the anniversary of the deadliest single attack on Jewish people since the Holocaust. This decision, widely seen as symbolic and controversial, drew criticism for perceived insensitivity. Zoë Garbett, the mayor of Hackney, subsequently apologized for the timing but indicated the de-twinning would proceed.

The British government has taken steps to combat rising antisemitism. During his time as opposition leader, Sir Keir Starmer announced a £250 million funding package aimed at increasing police presence and security at Jewish sites. Now serving as prime minister, Starmer has also commissioned Sir David Bell, a retired senior civil servant, to lead an inquiry into antisemitism within the education sector, with findings expected this autumn.

Law enforcement agencies have intensified efforts to address hate crimes linked to protests, and officials such as Andy Burnham have expressed commitments to continue these interventions while exploring ways to hold social media companies accountable for online hate speech.

Despite these measures, experts highlight a persistent societal issue: the prevalence of anti-Jewish attitudes within segments of the population. Reducing the spread of hatred is seen as only an initial step, with greater emphasis needed on education across schools, universities, local governments, and workplaces. The routine presence of security at Jewish places of worship is cited as a stark reminder of the problem’s severity, underscoring calls for a concerted and coordinated response to confront what remains one of the oldest forms of prejudice.
