UK proscribes IRGC and proxies

What's happened

The UK has designated Iran’s Islamic Revolutionary Guard Corps (IRGC), the Islamic Movement of the Companions of the Right (IMCR) and Russia’s GRU Volunteer Corps as national security threats. Ministers have said the measures will criminalise support, broaden policing powers and enable prosecutions; Parliament must approve the regulations this week.

What's behind the headline?

What this means now

• The Home Secretary has laid regulations that will make public support for the IRGC, IMCR or GRU Volunteer Corps a criminal offence punishable by prison. Parliament must approve the designations before they take effect.
• Police and intelligence services are gaining expanded powers to investigate, charge and prosecute people who recruit, direct or carry out sabotage on behalf of those groups.

Why ministers acted

• Ministers are treating the IRGC as more than a conventional military force; they say it is conducting intelligence operations and directing proxy actors in Europe.
• The IMCR has publicly claimed a string of arson attacks on Jewish sites and Persian-language outlets in Britain, which the government links to IRGC Quds Force direction.

Likely outcomes

• Relations with Tehran will worsen. The government has previously warned that proscribing the IRGC would risk diplomatic retaliation, including the possible expulsion of the UK ambassador.
• Police will increase counter-proxy operations and prosecutions. The new powers will allow police to pursue not only attackers but also those who finance, direct or materially support proxy networks.
• The measures will push hostile activity further underground, increasing intelligence collection demands and likely prompting more covert disruption work.

Bottom line

The government has shifted from sanctioning to criminalising support for organisations it says are conducting hostile foreign activity on UK soil. That will force security services to prioritise tracking proxy networks and give prosecutors clearer tools to seek longer sentences.

How we got here

The move follows a new National Security (State Threats) Act that took effect this month. Authorities say the IMCR has claimed arson attacks on Jewish sites and Persian-language media in the UK and that the IRGC has used proxies and intelligence activity to target people on British soil.

Our analysis

The UK government’s position appears consistently across outlets. Home Office and ministerial statements quoted by Reuters and the BBC set out the legal mechanics: the National Security (State Threats) Act has enabled regulations that "will make it easier to prosecute and lock up anyone carrying out their dirty work here in Britain," Prime Minister Keir Starmer said (Reuters). The BBC reported that the Home Secretary has said expressing a positive opinion of the IRGC or assisting it will now be an offence punishable by up to 14 years. Reporting in The Times of Israel and UK outlets supplied operational details and local reaction. The Times of Israel and the New York Post noted that police have arrested a suspect, Vahid Aberi, and carried out searches in Liverpool and Birmingham; police said they had not identified a direct threat to a specific community but have increased national security investigations (Times of Israel). The Guardian and The Independent traced the move to a series of threats and plots attributed to Iran-linked actors and noted that ministers believe the IRGC’s Quds Force has directed IMCR attacks across Europe. Commentary outlets such as The Scotsman emphasised political accountability, recalling MI5 assessments that identified dozens of plots linked to Iran. The collection of reports shows broad government consensus on the security rationale and wide coverage of the legal and policing consequences; coverage differs mainly in tone and emphasis on diplomatic fallout versus domestic law enforcement action.

• Quds Force - Iranian Islamic Revolutionary Guard Corps unit

  The Quds Force (Persian: نیروی قدس, romanized: niru-ye qods, lit. 'The Jerusalem Force') is one of five branches of Iran's Islamic Revolutionary Guard Corps (IRGC). Considered an elite unit within the IRGC, it specializes in unconventional warfare and military intelligence operations. U.S. Army General Stanley McChrystal describes the Quds Force as being analogous to a combination of the United States' CIA and the Joint Special Operations Command (JSOC). Responsible for extraterritorial operations, the Quds Force has been described as the IRGC’s de facto external affairs branch. It supports non-state actors in many countries, including Hezbollah, Hamas, Palestinian Islamic Jihad, the Houthis, and Shia militias in Iraq, Syria, and Afghanistan; it has also deployed personnel in foreign conflicts such as the Syrian Civil War and the Iraqi offensive against Islamic State. The Quds Force reports directly to the supreme leader of Iran, currently Mojtaba Khamenei since 8 March 2026. After Quds Force commander Qasem Soleimani was assassinated in a U.S. drone strike in January 2020, his deputy, Esmail Qaani, replaced him.
