GCHQ

Available for over a year

On January 25, 1984, Foreign Secretary Geoffrey Howe announced plans to ban trade union membership at the government communications centre in Cheltenham. Senior civil servants and former CGHQ employees recall their roles in the resulting industrial dispute, which lasted for years and thrust this covert surveillance centre firmly into the public limelight. Contributors include Roy Hattersley and Howe himself. Chris Ledgard presents.
