Sir Maurice Oldfield GCMG CBE (16 November 1915 – 11 March 1981)[1] was a British intelligence officer and espionage administrator.

[4] He was educated at Lady Manners School at the nearby market town of Bakewell, before winning a scholarship to the Victoria University of Manchester, where he stayed at Hulme Hall.

On his return, he became director of counter-intelligence and deputy to the Chief of the Secret Intelligence Service Sir Dick White.

[12] A large explosive device was discovered by officers from Special Branch hanging on railings outside Marsham Court on 13 October 1975.

[6] After his retirement as Chief of the SIS, it emerged that Oldfield was homosexual, resulting in his security clearance being withdrawn shortly before his death in 1981.

[17][2] In his memoir The Pigeon Tunnel: Stories from My Life Le Carré describes a lunchtime meeting between Oldfield, himself and Alec Guinness; this was intended to provide the actor with a sense of the manner and appearance of an "old spy in retirement".

[18] In October 2012, it was reported by the BBC's current affairs programme Panorama, that he had been linked to the Elm Guest House child abuse scandal, supposedly involving senior MPs and security personnel, by the Operation Midland investigation, and a Metropolitan Police informant.
