Michael John Bettaney (13 February 1950 – 16 August 2018),[1] also known as Michael Malkin, was a British intelligence officer who worked in the counter-espionage branch of the Security Service often known as MI5.
He was convicted at the Old Bailey in 1984 of offences under section 1 of the Official Secrets Act 1911 after passing sensitive documents to the Soviet Embassy in London and attempting to act as an agent-in-place for the Soviet Union. His trial was conducted in camera but some of the press reporting is available.[2]
