The spy agency, GCHQ, has employed thousands more members than they have publicly disclosed, as it endeavours to include cyberthreat from terrorists, hostile states and organised crime.
According to an official report from the previous year, the Spy centre had employed nearly 5,700 full-time staff and officers at its headquarters in Cheltenham, as well as their satellite stations across Britain.
GCHQ has promised more transparency about its work.
