The Foreign Office maintained a number of wireless intercept (Y) stations at various strategic locations overseas in the years before the start of the Second World War. These stations, manned by FO staff, worked from 1938 to priorities established by the inter-departmental Y Committee, rather than by the FO. FO staff also did some traffic analysis and evaluation work overseas under GC&CS direction.
