Thousands attend annual commemoration as displays linked to Iranian leaders raise questions following new UK security legislation
LONDON: Posters of Iranian leaders and flags associated with Iran’s political establishment appeared during Sunday’s Arbaeen Procession in London, drawing attention amid recently introduced British legislation targeting foreign state threats.
The annual procession commemorates Imam Hussain, grandson of Prophet Muhammad, who was martyred at Karbala in 680 CE. Arbaeen marks the 40th day after his martyrdom and commemorates his stand against oppression and injustice.
Hussaini Islamic Trust UK organised Sunday’s procession near Marble Arch and estimated that about 35,000 people attended. The organisation described it as the largest gathering in the event’s 46-year history in Britain.
However, photographs and videos reviewed by The Jerusalem Post showed participants carrying posters depicting Iranian leaders, alongside numerous Iranian political flags.
IHRC Material Appears During Procession
Among the displays was a poster attributed to the Islamic Human Rights Commission carrying the message “Choose the right side of history” alongside an image of an Iranian leader.
The UK Charity Commission has investigated the IHRC since 2017 over concerns about its activities and alleged Iranian links.
Furthermore, the watchdog issued an official warning in March 2023 following an investigation into alleged misconduct or mismanagement. The case reportedly remains ongoing.
New Security Law Raises Legal Questions
The displays also attracted scrutiny following Britain’s adoption of the National Security (State Threats) Act 2026 in July.
Under the legislation, authorities can designate organisations allegedly involved in foreign state-threat activities.
Britain subsequently designated Iran’s Islamic Revolutionary Guard Corps on July 17, making certain expressions of support for the organisation a criminal offence.
However, whether displays depicting Iranian political or religious leaders fall within those restrictions remains a legal question.
The Jerusalem Post said it contacted London’s Metropolitan Police seeking clarification about whether authorities took action during the procession.
Meanwhile, British MP Nick Timothy criticised the displays and accused participants of openly celebrating Iran’s government.
