HC Deb 23 July 1979 vol 971 c26W
Mr. Kilroy-Silk

asked the Secretary of State for the Home Department on how many occasions in the last year for which figures are available letters to or from prisoners have been referred to headquarters for a decision on whether or not they can be allowed.

Mr. Brittan

The information requested is not readily available and could only be obtained at disproportionate cost.
