Prison Establishments (Nursing Cover) Mrs. Renée Short asked the Secretary of State for the Home Department whether it is the policy of Her Majesty's Government to provide 24-hour on-call nursing cover in all prison establishments. Mr. Mellor No. It is the policy of the Director of Prison Medical Services to provide 24-hour medical cover in all establishments and 24-hour nursing cover in those establishments where that is judged to be necessary.
