HC Deb 29 June 1943 vol 390 c1476W
Captain Plugge

asked the Prime Minister whether, in view of public concern, he is satisfied that full precautions are taken not to disclose the movements of distinguished personages abroad until sufficient time has elapsed to make the information published of no value to the enemy?

Mr. Attlee

Yes, Sir; the fullest precautions are taken, but the maintenance of secrecy in these matters depends also on the discretion of all who may inadvertently learn something which leads them to surmise that such movements have taken place.
