The UK government proscribes Iran’s Islamic Revolutionary Guard Corps (IRGC) as a terrorist organisation, according to reports. Prime Minister Keir Starmer has ordered the designation, citing concerns about threats to life and intimidation connected to activities on UK soil. The decision means the IRGC is treated under UK law as a terrorist group, with implications for how individuals and organisations can engage with or support it. The move aligns with the UK’s approach to counter-terrorism designations, which are based on risk and evidence related to violence, threat, and intimidation. Reporting indicates the designation is framed around alleged conduct that affects people in the UK rather than focusing on any single incident. Further details of the legal and evidential basis, as well as the practical effects for authorities and the public, are not included in the available excerpts. The designation is presented by the UK as a security measure responding to risks attributed to the IRGC’s actions and impact within the UK.
