 Interview with Meredith Gardner by Christopher Andrew, broadcast in the BBC Radio 4 documentary
VENONA
. Claims that Philby made further visits to AFSA and looked over Gardner's shoulder as he decrypted VENONA are inaccurate. A Security Service report in 1986 concluded that, âapart from Weisband and Philby there are no known spies who had access [to VENONA].' Security Service Archives.

 Because of lack of usable evidence, Weisband was never prosecuted for espionage. After his suspension from AFSA on suspicion of disloyalty, he was convicted of contempt for failing to attend a federal grand jury hearing on Communist Party activity and sentenced to a year's imprisonment (Benson and Warner (eds),

 Initially the Treasury had envisaged that the cases of all those purged should be referred to a senior civil servant who would co-ordinate policy in the operation of the procedure. The other founder members of the Tribunal, in addition to Gardiner, were Sir Frederick Leggett and Sir Maurice Holmes, both retired civil servants. Holmes was soon replaced by W. J. Bowen, an ex-trade unionist, but continued to act as a reserve in the absence of any other member of the board. Security Service Archives.

 It was originally envisaged that those sacked in the âIndustrial Purge' would be given a right of appeal, similar to that enjoyed by government servants. However, this concept was abandoned on the advice of both the TUC and employers as represented on the National Joint Advisory Council. Sackings were rare and handled by the industrial section, C2, in consultation at first with B1D (Communism in industry). Security Service Archives.

 Two other committees reported to the Official Committee: the Personnel Committee (previously the Positive Vetting Committee), chaired by the Treasury, and the Committee on General Security Procedures, under the chairmanship of the Home Office. A Security Service officer, the Hon. J. L. Vernon, was seconded to the Cabinet Office in December 1953 to serve as secretary of both committees. The Personnel Committee, with Director C as the Service representative, worked comparatively smoothly. The Committee on General Security Procedures did not. In 1957, after the exasperated Security Service representative, Michael Serpell (C1), complained to the Home Office that it had not met for nearly two years, it was replaced by a new and more active Security (Policy and Methods) Committee, which also subsumed the JIC Security Committee.
