LONDON: The UK will not proscribe Iran’s Islamic Revolutionary Guard Corps as a terrorist organization, the Daily Telegraph reported on Thursday.

The stance was reportedly relayed by UK Foreign Secretary David Cameron during a face-to-face meeting with Israeli Prime Minister Benjamin Netanyahu and Foreign Minister Israel Katz on Wednesday.

The Israeli government reportedly requested that the UK ban the IRGC following Iran’s drone and missile attack last week.

But Cameron, in what a source called a “blunt” response, told Netanyahu and Katz that doing so would hinder London’s ability to communicate with Tehran.

“We need to be able to pick up the phone. If we proscribed them it would not help the situation,” the source reported Cameron as saying.

If the IRGC were to be proscribed in the UK, it would make membership of it, attending its meetings, displaying its symbols or campaigning for it in the country illegal.

The move has been considered by the UK government for over a year, but Home Office officials have long warned that doing so would sever one of the few remaining diplomatic channels with Tehran. Instead, the IRGC has been sanctioned by the UK government on several occasions.

The US, which has banned the IRGC, has also suggested that the UK should proscribe it. The group’s navy was recently included in a new set of joint sanctions issued by London and Washington.
