HC Deb 15 February 1944 vol 397 c43W
Mr. Silkin

asked the Minister of Information by what authority letters sent by civilians from one part of the United Kingdom to another are opened and examined by the censor.

Mr. Bracken

The censorship of inland mails is carried out under the Royal Prerogative. An announcement was made on 17th July, 1942, to the effect that, in the interests of operational security, censorship might be applied from time to time to communications from areas in the neighbourhood of ports, aerodromes and other localities of operational importance.
