'''''R v Aubrey, Berry and Campbell''''', better known as the '''ABC Trial''', was a trial conducted in the United Kingdom in the 1970s, of three men for offences under the [[Official Secrets Act 1911]]. The men were two [[libertarian]] journalists of a similar political viewpoint as much of the [[Labour Party (UK)|Labour]] government, and a resigned [[GCHQ]] source seeking to heighten scrutiny of government-authorised wire-tapping and limit the work of the American espionage agency, the [[Central Intelligence Agency|CIA]], in Britain. These aims were furthered in the following two decades achieved through detailed parliamentary scrutiny into and regular reports as to the work of security services, a Freedom of Information Committee and regulation of wire-tapping. Aside from very limited reportage from the [[Central Criminal Court (England and Wales)|Central Criminal Court]], its early analysis comes in the account of one of its investigative-journalist defendants, [[Duncan Campbell (journalist, born 1952)|Duncan Campbell]], in the annual journal ''[[Socialist Register]]''.
