Mr Farage said the Government could also strengthen its relationship with the new US administration by inviting Mr Trump for a state visit next summer.

He also warned that the incoming Trump administration would be “quite dismayed” by the British cession of the Chagos Islands to Mauritius.

“I have spoken to people in and around the administration at a very, very high level who are simply astonished that the UK is doing this for no gain, only with a misconception of international law where a few lawyers of human rights meet at the UN,” Mr Farage said.

The prime minister was also pressured to ban the IRGC by members of his own party.

Pro-Israel Labor MPs told the government that banning the group was the first item on a “menu of options”, according to The Telegraph.

In response to private representations on the issue, ministers insisted that individual sanctions against Iranian regime figures are more effective than a total ban on the IRGC in Britain.

Right-wing Labor Party MPs say banning the IRGC could offset the government’s perceived anti-Israel moves, including its decision to restore funding to UNRWA, the UN’s Palestinian aid agency, and to suspend certain arms export licenses to Israel.

Murder-for-hire conspiracy

The US Department of Justice (DoJ) revealed on Friday that it had foiled a murder-for-hire plot ordered by the IRGC in revenge for Mr Trump’s fatal 2020 attack on Qassim Soleimani, one of his commanders .

Justice Department officials waited days after Mr. Trump’s landslide victory at the White House to reveal that there had been another assassination attempt on the president-elect.

Mr. Trump survived two other known assassination attempts this year.

In July, Thomas Crooks fired bullets that grazed the president-elect’s ear as he addressed a rally in Pennsylvania, killing one bystander and wounding two others.

In September, Ryan Routh allegedly monitored Mr Trump’s golf course for 12 hours with a semi-automatic rifle, but was spotted by the US Secret Service before he was able to open fire.
