'The Doughnut', the GCHQ building at Benhall, Cheltenham.

Government Communications Headquarters (GCHQ) is a British signals intelligence (sigint) agency.

History

Government Code & Cypher School

The Government Code & Cypher School (GC&CS) was founded in 1919 as Britain's first integrated cryptographic agency.

GC&CS was redesignated the London Signals Intelligence Centre in 1946, following a move from its wartime centre at Bletchley Park to Eastcote.

GCHQ

The organisation formally took the name Government Communications Headquarters (GCHQ), previously in use as a cover name, on 1 November 1948.

ABC Trial

GCHQ's activities received little publicity until 1976, when Duncan Campbell probed its activities in Cyprus for Time Out magazine. The subsequent prosecution under the Official Secrets Act became known as the ABC Trial.

Geoffrey Prime affair

A former GCHQ employee Geoffrey Prime was convicted of spying for the KGB in 1982.

The Zircon project

British dependence on American satellites during the Falklands War led GCHQ director Brian Tovey to propose a British spy satellite, Zircon.

In early 1987, BBC director general Alisdair Milne, banned a documentary by Duncan Campbell, who had discovered the existence of the Zircon project and the fact that Parliament knew nothing about it.

By 1988, the British government opted instead to pay £500 million to guarantee access to American satellites.

Union ban

Trade unions were bannned from GCHQ by the Thatcher government in January 1984, prompting a long-running dispute.
