Editing Jonathan Aitken (section)

===Hollis affair===
Aitken wrote a highly confidential letter to Thatcher in early 1980, dealing with allegations that the former Director-General of [[MI5]], Sir [[Roger Hollis]], had been a double agent also working for the [[Soviet Union]]. This information had come to Aitken from retired [[CIA]] spymaster [[James Angleton]]. Espionage historian [[Chapman Pincher]] obtained a copy of the letter, and used former MI5 officers [[Peter Wright (MI5 officer)|Peter Wright]] and Arthur Martin as his main additional secret sources, to write the sensational book ''Their Trade is Treachery'' in 1981. This matter continued to be highly controversial throughout the 1980s, and led to Wright eventually publishing his own book ''[[Spycatcher]]'' in 1987, despite the government's prolonged Australian court attempts to stop him from doing so.<ref>''A Web of Deceit: The Spycatcher Affair'', by [[Chapman Pincher]], London 1987, Sidgwick and Jackson, {{ISBN|0-283-99654-4}}</ref>
