British Prime Minister Keir Starmer has pledged to introduce legislation within weeks to formally ban Iran’s powerful Revolutionary Guards, according to remarks published Friday.

Speaking to the Jewish Chronicle during a visit to a London synagogue targeted in a recent arson attack, Starmer said the government is preparing legal measures to proscribe the Islamic Revolutionary Guard Corps as a terrorist group.

“We do need legislation to take necessary measures, and that is legislation that we’re bringing forward as soon as we can,” Starmer said, adding the proposal would be introduced in the next parliamentary session.

Move follows European action

The planned legislation comes after the European Union agreed in January to designate the IRGC a terrorist organization over its role in suppressing mass protests in Iran.

The IRGC, established after Iran’s 1979 revolution, is a central pillar of the country’s security apparatus and wields significant economic and political influence.

Security concerns rise in UK

Starmer’s comments come amid heightened concern over security in Britain following a series of arson attacks targeting synagogues and Jewish community sites in northwest London.

The incidents have left residents on high alert and prompted calls for stronger action against foreign-linked threats.

Starmer said he is increasingly worried about “malign state actors” using proxies to carry out criminal activities in the UK.

Broader crackdown signaled

The proposed legislation would give authorities expanded powers to restrict the activities, financing and support networks linked to the IRGC.

It also reflects a broader shift in Britain’s approach to Iran, as tensions rise following recent U.S. and Israeli military actions and their wider regional fallout.

Further details of the legislation are expected when Parliament reconvenes in the coming weeks.
