HC Deb 20 November 1986 vol 105 c311W
Mr. Irving

asked the Secretary of State for Foreign and Commonwealth Affairs how many employees at Government communications headquarters have joined the staff federation; and what proportion of the total number of employees this represents.

Mr. Renton

It is not the practice to reveal details of the strength of the security and intelligence agencies, but I can inform my hon. Friend that more than 49 per cent. of the staff at GCHQ have now joined the Government communications staff federation. This is a higher percentage than ever previously belonged to any single union at GCHQ.
