HC Deb 08 July 1981 vol 8 c126W
Mr. Dubs

asked the Secretary of State for the Home Department what is his estimate of the number of prison officers involved and the number of man hours devoted annually to the censorship of prisoners' correspondence in penal institutions.

Mr. Mayhew

In many establishments censorship is only one of a number of tasks carried out by wing officers in the course of the day. To count the number of officers who have been involved in censorship in any one year or to isolate the time spent on censorship would therefore involve disproportionate cost.
