Islamic Revolutionary Guard Corps operatives are heading to Britain, claims Nigel Farage’s Reform UK.
The party’s home affairs spokesman Zia Yusuf made the allegation about Iran’s hardline military force as the number of migrants crossing the Channel from France to Britain rises as the weather improves.
“It’s no secret that Britain’s enemies have been exploiting the small boats crisis,” Mr Yusuf told the Standard.
“Military aged Iranian men are streaming across the Channel.
“Some almost certainly IRCG operatives,” he added, stressing that the security services had already thwarted more than 20 terror plots linked to Tehran in a year, including several in London.
More than 20 people have been arrested over the recent spate of arson attacks on synagogues and other Jewish-linked sites in the capital.
Police say most of them are British-born, including "thugs for hire“ rather than foreign agents who have recently come into the country.
Many of the Iranians trying to reach Britain are also likely to be people fleeing the Tehran regime.
All people arriving in the UK illegally on “small boats” face having to undergo stringent security checks.
A Home Office spokesperson said: “This government has been clear, border security is national security.
“We take all allegations of abuse of the immigration system extremely seriously and will not hesitate to take appropriate action where necessary.
“Where an individual is identified as a threat, authorities will take the necessary action, including denying protection to those who are a threat to national security, and removing them as swiftly as possible.”
Mr Yusuf made the claim about IRGC infiltration into the country as the UK’s anti-terror laws chief Jonathan Hall said it appeared that Tehran was masterminding a string of arson attacks on locations with Jewish links in London.
The security services are investigating whether a shadowy group called Harakat Ashab al-Yamin al-Islamia, the Islamic Movement of the Companions of the Right, may be carrying out the “dirty work” of the Tehran regime, Mr Hall added, by recruiting people in London and other parts of the UK to commit crimes.
Mr Yusuf stressed: “Given the recent and savage attacks on London’s Jewish community since the war in Iran started, the Government’s inability to get a grip on the Channel presents a very real and active threat not just to our national security, but also to Jews across the UK.”
Scotland Yard has said MI5 and counter-terrorism police have foiled more than 20 Iranian state-backed attacks on the UK in a year.
Individuals, including Iranian journalists highlighting the brutality of the Iranian regime, have been targeted in plots by Tehran.
Last month counter-terrorism officers arrested four people under the National Security Act after they allegedly spied on Jewish communities in the capital for the Iranian regime.
Sir Keir Starmer has sought to stop Britain being dragged into Donald Trump’s Iran war.
The Government refused permission for US planes to use RAF bases for the initial and offensive attacks on Iran.
The Prime Minister later gave consent for the American forces to use British bases for “defensive” operations, such as targeting Iranian missile sites, after British citizens, military personnel and interests came under attack from airstrikes by Tehran.
This authority was later extended to US missions to try to reopen the Strait of Hormuz.
But despite this nuanced stance by the Government, many in the Tehran regime still regard Britain as the “Little Satan” supporting America.
As the war escalated, Iran fired two missiles at the joint UK-US Diego Garcia base on the Chagos Island, a distance of nearly 2,500 miles.
The attack failed but it sparked warnings, including from Israel, that European capitals including London, may now be in reach of Iranian missiles.
Military experts say that if this was the case the explosive payload on the missiles would have to be so small, to keep down the weight, that they would have limited impact.
Cabinet ministers insisted that any missile fired at London would be shot down by Nato’s security network, including defences based in eastern Europe.
But former UK National Security Adviser Lord Sedwill suggested that an Israel-style “Iron Dome” may needed over London to protect the city.
Ex-military commanders say Britain is not prepared to respond to a missile attack on the homeland.
