HC Deb 25 January 1979 vol 961 c200W
Mrs. Renée Short

asked the Secretary of State for the Home Department if he will list the 27 areas of interest under which the Special Branch's computer system will eventually store information.

Mr. Merlyn Rees

In general, they relate to aspects of the protection of the security of the State, which it would not be in the public interest to specify. I remind my hon. Friend that the recently published report of the data protection committee recognises that special consideration must apply to computer data involving national security.
