HC Deb 01 August 1975 vol 896 c649W
Mr. Lawrence

asked the Secretary of State for the Home Department what is the total number of letters to Members of Parliament from prisoners in Her Majesty's prisons which have been stopped by the prison authorities in each of the past five years.

Dr. Summerskill

I regret that the information is not available and could not be obtained without disproportionate cost.
