Harold Wilson conspiracy theories

Since the mid-1970s, a variety of conspiracy theories have emerged regarding British Labour Prime Minister Harold Wilson, who served as the Prime Minister of the United Kingdom from 1964 to 1970 and 1974 to 1976, winning four general elections. These range from Wilson having been a Soviet agent (a claim which MI5 investigated and found to be false), to Wilson being the victim of treasonous plots by conservative-leaning elements in MI5, claims which Wilson himself made.

Soviet defector Anatoliy Golitsyn is said to have told Alec MacDonald, who set up safe houses where Golitsyn could live, that Wilson was a KGB operative and that former Labour Party leader Hugh Gaitskell had been assassinated by the KGB to have the pro-US Gaitskell replaced as party leader by Wilson.Guardian journalist David Leigh, however, claims that Golitsyn was guessing.Christopher Andrew, the official historian for Britain's MI5, has described Golitsyn as an "unreliable conspiracy theorist".

In his controversial 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 1964. Wright said that Angleton said he had heard this from a source (whom he did not name but who was probably Golitsyn). 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.
