An estimated 20,000 people gathered in central London on Sunday for an intercommunal show of solidarity against rising antisemitism.

The Combat Antisemitism Movement (CAM) was proud to be among the co-organizers of the rally, held outside the British Prime Minister’s Residence on Downing Street.

At the event, UK Chief Rabbi Ephraim Mirvis warned that “poisonous antisemitism has become normalized in the UK.”

“It is unacceptable that our communities can only function behind high fences and with security guards,” Rabbi Mirvis said. “It is unacceptable that social media platforms continue to spew out Jew hatred with impunity. It is unacceptable that Iran is inspiring violence against British citizens on British soil.”

Rabbi Mirvis also called for the expulsion of the Iranian ambassador from the UK and the blacklisting of the Islamic Revolutionary Guard Corps (IRGC) as a terrorist group.

Executive Director of European Affairs Shannon Seban participated in the demonstration on behalf of CAM.

“There were Jews and non-Jews standing together at this rally, united by the understanding that the fight against antisemitism is a universal cause — and precisely the kind of unity we need today,” Seban said.

“Antisemitism is also a symptom of democracies becoming unwell, which makes this struggle everyone’s responsibility,” she added. “What I felt there was deep emotion, but not victimhood — rather, profound resilience and, above all, a determination to keep fighting.”

Since the start of 2026, the Antisemitism Research Center (ARC) by CAM has tracked 620 antisemitic incidents in the UK — nearly 20% of all incidents documented worldwide so far this year.

Just two weeks ago, two Jewish men were seriously wounded in an antisemitic stabbing attack in London’s Golders Green neighborhood.

Recent months have also seen multiple London area synagogues targeted by arsonists, with the shadowy Iran-linked terrorist network, Ashab al-Yamin al-Islamia (“The Islamic Movement of the Companions of the Right”), claiming responsibility for some of the attacks.

Last October, on Yom Kippur, a ramming and stabbing attack perpetrated by an Islamist terrorist left two Jewish worshipers dead at a synagogue in Manchester.

Noteworthy in the crowd on Sunday was a numerous contingent of anti-Iranian regime activists, highlighting shared struggles and aspirations with the Jewish community.
