‘This is Tehran’: Khamenei posters and Iran regime flags displayed at London march

What Happened

During an Arbaeen Procession in London on Sunday, participants displayed posters of Supreme Leader Ayatollah Ali Khamenei and flags associated with the Iranian regime. The event, organized by the Hussaini Islamic Trust UK, drew an estimated 35,000 attendees. The Jerusalem Post reported that the Islamic Human Rights Commission (IHRC) distributed materials featuring Khamenei, while other individuals wore imagery depicting current and former Iranian leaders. These displays occurred following the UK government's July 2026 designation of the Islamic Revolutionary Guard Corps (IRGC) as a prohibited organization under the National Security (State Threats) Act 2026, which criminalizes support for the group.

Why It Matters

The public display of Iranian state symbols in London highlights ongoing domestic debate regarding the enforcement of the National Security (State Threats) Act 2026. Because the Supreme Leader holds ultimate authority over the IRGC, legal experts and political figures are debating whether such displays constitute criminal support for a designated terrorist organization, testing the boundaries of the new legislation.

Watch For

Monitor potential statements from the UK Home Office or the Metropolitan Police regarding whether the displays meet the threshold for prosecution under the 2026 Act, as well as any updates from the UK Charity Commission's ongoing investigation into the IHRC.
