Mark Thatcher is the son of British Prime Minister Margaret Thatcher.¹ He is an established arms dealer with significant connections in the international arms trade, particularly with Chile and South Africa.²

In 1983, Thatcher introduced Gerald Bull to Pieter Van Der Westhuizen, chief of South African Defense Force, who then connected Bull with Armscor for his "supergun" project.²

Thatcher was present at a meeting in Santiago, Chile, in late 1986 with Carlos Cardoen, Robert Gates, Senator John Tower, and Gen. Pieter Van Der Westhuizen, where the United States reaffirmed its intention to maintain arms channels to Iraq through South Africa and Chile.²

Cardoen indicated that Thatcher was involved in his business, and that he had the backing of the Americans and the Chilean government. Thatcher also had business dealings with South Africa for a long time, and was involved in providing military equipment through the Cardoen network to the Iraqis, including nuclear missile projects.²

In 1988, Ari Ben-Menashe met Thatcher in Santiago, Chile, where Thatcher presented himself as a private businessman with no connection to the British government, despite his mother's position. He expressed admiration for Augusto Pinochet and discussed the Falklands War, noting Chile's support for United Kingdom. He also revealed that Cardoen received technology directly from the Central Intelligence Agency through Gates's office.²

Thatcher was involved in the sale of 48 Chieftain tanks to Chile after the Falklands War. He was also linked to Ihsan Barbouti and Sarcis Sargalian in projects supplying Iraq with military equipment. Richard Babayan, a CIA contract agent, also controlled a network providing equipment for Iraq.²

Al-Yamamah allegations

On January 24, 1996, George Galloway told the Commons that commissions on the Al-Yamamah arms sales had been paid through middlemen, and named Mark Thatcher and Wafic Said among them. He described Mark Thatcher as "the son of the then Prime Minister, who gave 10 Downing street as his address at the time," who "was later given his own house and other lavish benefits by Wafic Said." Galloway also named Douglas Leese among the intermediaries and described Jonathan Aitken as Said's business partner.³ The writer Paul Foot wrote in 1998 that it had become "common knowledge" that Mark Thatcher enriched himself by £12 million from the Al-Yamamah deals, that Thatcher himself never denied it or sued anyone for mentioning it, and that no one, including the authors of a book on the subject, could produce a single hard fact to prove it.⁴ The Guardian wrote in 2006 that it had been alleged that Thatcher's son received secret commissions from the deal and that all those involved had always denied the allegations.⁵

Equatorial Guinea plea of 2005

On January 13, 2005, in the Cape High Court in Cape Town, Mark Thatcher pleaded guilty under a plea agreement to attempting to contravene section 2 of South Africa's Regulation of Foreign Military Assistance Act by agreeing to charter a helicopter, for which he paid $275,000. The text of the agreement stated: "The accused began to suspect that the helicopter might in fact be intended for use in ... mercenary activity [in the west African region]. Despite his misgivings the accused decided to invest money in the charter of the helicopter." His lawyers stated that he was not charged with any involvement in the attempted coup in Equatorial Guinea. Judge Abe Motala imposed a fine of three million rand, or five years in prison, and a further four-year sentence suspended for five years. Zimbabwe had jailed Simon Mann, a friend of Mark Thatcher and a former British special services officer, with 65 other suspected mercenaries in September 2004.⁶⁷
