The UK government has designated Iran's Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization, citing its involvement in antisemitic attacks and threats to national security. The ban, announced on July 13, 2026, also targets the Iran-linked group Ashab al-Yamin al-Islamiya, making support for these organizations a criminal offense with limited exceptions. Prime Minister Keir Starmer emphasized the decision was necessary to counter state-backed threats on British soil.Reuters+2
The Home Office will enforce the ban using new legal powers targeting state threats, with Justice Secretary Shabana Mahmood overseeing implementation. Authorities linked the IRGC to violent plots including arson attacks on Jewish sites and intimidation of Iranian dissidents. The move aligns the UK with other nations that have previously proscribed the IRGC.RIA Novosti+2
The decision escalates tensions with Tehran, coming on the same day as Iran's military parade commemorating the Iran-Iraq war. UK officials accused the IRGC of orchestrating attacks through proxy groups, while Iranian state media condemned the ban as politically motivated. The conflict reflects broader Western concerns over Iran's regional influence.The New York Times+2
Supporting the IRGC or Ashab al-Yamin al-Islamiya now carries potential criminal penalties, though exemptions exist for diplomatic, journalistic, and humanitarian activities. The proscription allows authorities to freeze assets and prosecute individuals affiliated with the groups. Legal experts note this marks the UK's strongest action yet against Iranian state entities.BBC News+2
British security services highlighted the IRGC's alleged involvement in assassination plots against Iranian journalists and activists in the UK. The ban enables enhanced monitoring of financial transactions and communications tied to the groups. Analysts warn this could provoke retaliatory measures from Tehran.The Washington Post+2
