§ Mr. Campbell-Savoursasked the Secretary of State for Defence on how many occasions the secretary of the D Notice committee has advised publishers of books that material in books they are proposing to publish contains information on the security services which cannot be published; and in the case of which books.
§ Mr. FreemanSince 1967 the secretary of the defence press and broadcasting committee has offered advice to publishers of 36 books that some amendments should be made on grounds of national security. However, discussions between the secretary of the defence press and broadcasting committee and the press, broadcasting authorities and publishers are regarded as having taken place in confidence, and I do not therefore intend to name the books concerned.
