UK bans support for Iran's IRGC as national security threat
The UK government has announced that Iran's Islamic Revolutionary Guard Corps will be designated a threat to national security. The move means support for the group will be banned under new powers, with penalties of up to 14 years in prison. The announcement was made by Home Secretary Shabana Mahmood in a written statement to Parliament.

According to the statement, support for the IRGC will cover conduct ranging from expressing a positive opinion to assisting the organisation. The government said the group has been linked to death threats and intimidation in the UK. Two other groups are also being proscribed: the Islamic Movement of Companions of the Right and the volunteer corps of Russia's GRU, the country's foreign military intelligence agency.
The decision marks a significant step in the UK's national security policy toward Iran. Proscription gives authorities wider powers to restrict support for a group and to pursue criminal penalties against those who back it. By setting a maximum sentence of 14 years, ministers are signalling that they view the issue as a serious security matter rather than a purely diplomatic dispute.
The IRGC is one of the most powerful institutions in Iran and has long been a focus of concern for Western governments. In the UK, the government said the group has been associated with intimidation and threats, which has added urgency to the move. The inclusion of two other organisations in the same announcement suggests a broader effort to use existing legal powers against groups seen as hostile to UK interests.

The announcement also places Parliament at the centre of the next stage, as the legal and practical effects of the designation take shape. It is not yet clear how quickly enforcement will begin or whether further measures will follow. The government has said support for the IRGC will now be treated as a criminal offence, but the full operational impact will depend on how the new rules are applied.
What remains to be seen is how the designation will affect UK-Iran relations and whether it will prompt any response from Tehran. The statement did not set out further details on the evidence behind the decision beyond the references to threats and intimidation. More information is expected as the government and Parliament move to implement the ban.
