The villa is located in the country’s south-eastern region, about 40 kilometres from the capital, Tehran, where Iran’s ruling clerical establishment maintains a tight grip on politics.
But it has also been an open secret for decades, with a local historian claiming it was a favourite of Ayatollah Ruhollah Khomeini, who ruled Iran between 1979 and 1989.
In 2009, a group of historians and journalists uncovered a trove of documents from the period that showed the villa was used as a base for anti-US activity, and that a British spy had worked there as early as the 1950s.
But in the years since, the villas name has come to symbolise something far more sinister, as it has been used to mask the true identity of a vast secret army, which the British government has accused of being working with the US in its ongoing military operations in Iraq.
The villas true name is the Akhmed Khomeinist (Arabic: يارسم), and the group’s founder, Abdollah Khomeni, is widely regarded as a founding member of the secret paramilitary unit known as the Islamic Revolutionary Guard Corps (IRGC).
Khomeni was known for being a fierce critic of the Shah’s rule and his role in the 1979 Iranian Revolution, and his wife, who was the daughter of the notorious Hassan Pahlavi, the first head of the IRGC and Iran’s revolutionary guard.
The British Foreign Office, however, has maintained for years that the villases true name was “a secret and illegal” organisation.
“It was not the case that the Akhsmed Khomenis political party was responsible for the secret presence of the Islamic Revolutionaries,” a spokesman told the BBC last year.
But in an interview with the BBC’s Andrew Marr Show in January, Khomenen denied the existence of the organisation.
“The existence of this organisation is a myth,” he said.
“They are liars, the British embassy in Tehran, which is also a secret and secret organisation, has never said anything about it.”
In a rare interview with The Guardian in April, a senior British intelligence official said the existence or existence of Akhms secret organisation was a “very, very, very serious accusation”.
“They are a political party that have been operating in Iran for the last 40 years.
There’s no question of them being an active organisation,” the official said.
According to The Guardian, the Akhmens political party has “many offices” and has “membership in the Revolutionary Guards of Iran” and “is also closely linked with the CIA and other agencies”.
Despite the denials, the British Foreign Secretary has previously acknowledged the existence and activities of a secret group, which it said was responsible “for the systematic killing of thousands of people” by the Revolutionary Guard.
But the Guardian has reported that in 2013, a former British officer involved in Iraq operations was given access to a cache of intelligence reports from the British military intelligence service MI5, which revealed that the group had been targeting and assassinating Iranian dissidents since the 1980s.
In addition, Iran’s Revolutionary Guard has also been implicated in a number of attacks on British and American troops stationed in Iraq, including one carried out by an Iranian soldier in 2007 that killed four US soldiers and wounded more than 20.
The Guardian also reported that a former British soldier involved in Iraq attacks was jailed in 2015 for life for helping to organise a plot to bomb British and US troops in Iraq in the 1980-81 Gulf War.
According to the Guardian, British and British-Iranian diplomats are believed to have been involved in secret talks with the Iran Revolutionary Guard during the 1980 Gulf War.
This week, the Guardian reported that the British Foreign Minister said there was a possibility that Akhmen could be extradited to the UK.
Iran has long been accused of sponsoring terrorist activities against the UK and the US.
Last year, a report from the House of Commons intelligence committee said that Iran had provided training and money to the Taliban and al-Qaeda in Afghanistan.
But the US has denied any involvement in the terrorist activities of Iran.
Last year, Iranian officials said they were ready to allow the UK to extradite Abdelkader to the US, but had no further comment on the matter.
Iran’s foreign ministry did not respond to a request for comment.
