A group of 125 British MPs has signed a letter backing hunger striker Vahid Beheshti’s call for the Islamic Revolutionary Guard Corps (IRGC) to be outlawed.

The group supported the Iranian activist's call for the IRGC to be declared a terrorist organization in a letter they signed and sent to Prime Minister Rishi Sunak.

A group of the MPs backing Beheshti visited him in London on Wednesday as his hunger strike outside the Foreign Office entered its 56th day.

This comes as a series of protests are planned across London this month in support of Beheshti.

“Vahid has shown remarkable dignity and strength throughout his protest and has widespread support from parliamentarians who share his sense of urgency in the need to proscribe the (IRGC) as a terror organization,” read the letter addressed to Prime Minister Rishi Sunak, Foreign Secretary James Cleverly, and Home Secretary Suella Braverman.

“Proscription of the IRGC has deep support across Parliament. MPs unanimously endorsed a motion earlier this year calling for proscription. Peers from all parties and none have also joined the efforts to end the IRGC’s ability to operate in the UK.”

The government's decision to proscribe Hamas and Hezbollah terror groups was also noted by the group as an important step in combating extremism and terrorism, but the UK cannot afford to stop there.

“The IRGC is, after all, the primary financier, supplier, and trainer of these dangerous groups. It is incumbent upon the Government to go after the parent organization,” added the letter.
