HC Deb 26 November 1959 vol 614 c61W
87. Mr. A. Evans

asked the Secretary of State for the Home Department what instructions are given to the officials of Her Majesty's prisons regarding the giving of information about prisoners to unknown persons on the telephone.

Mr. R. A. Butler

The normal practice is to refuse to give information in response to a telephone inquiry and to invite the inquirer to submit his request in writing.
