HC Deb 17 March 1970 vol 798 c115W
Mr. Moonman

asked the Secretary of State for the Home Department if he will make a statement on the nature and extent of the records retained by his Department on persons who have political affiliations.

Mr. Callaghan

The security of the State necessarily requires that I should be in possession of certain information about political affiliations, which it would not be in the public interest to disclose.
