Government Communications Headquarters, commonly known as GCHQ, is an intelligence and security organisation responsible for providing signals intelligence (SIGINT) and information assurance to the government and armed forces of the United Kingdom. Based in "The Doughnut" in the suburbs of Cheltenham, GCHQ is the responsibility of the country's Secretary of State for Foreign and Commonwealth Affairs, but it is not a part of the Foreign Office and its director ranks as a Permanent Secretary.

"The Doughnut" is the nickname given to the headquarters of the Government Communications Headquarters (GCHQ), a British cryptography and intelligence agency. It is located on a 71-hectare (176-acre) site in Benhall, in the suburbs of Cheltenham, Gloucestershire, in South West England. The Doughnut houses 5,500 employees; GCHQ is the largest single employer in Gloucestershire.
