In his memoir "Spycatcher" (1987), former MI5 officer Peter Wright stated that the head of the CIA's Counterintelligence Division, James Angleton, told him that Wilson was a Soviet agent when Wilson was elected Prime Minister in the 1964 general election. Wright said that Angleton referred to this assertion coming from a source (whom he did not name but who was probably Golitsyn). Golitsyn's words had been frequently taken heed of by Angleton, who had grown suspicious of the loyalty of many political figures, such as Henry Kissinger. According to Wright, Angleton offered to provide further information on the condition that MI5 guarantee to keep the allegations from "political circles", but the management of MI5 declined to accept restrictions on the use of the information and Angleton told them nothing more.
