Memorandum from Sir Archibald Sinclair [Secretary of State for Air, later 1st Lord Thurso] to WSC on his censorship of Sir Walter Citrine [General Secretary of the Trades Union Congress and President of the International Federation of Trade Unions]: references were made to landmines on parachutes, of which one-third are duds; discussion in Press would alert the Germans into improving the device; suggests that Citrine is offended at not having received recognition for his broadcasts to the United States and praise from WSC would ease the situation.
