§ Dr. Lynne Jones
To ask the Secretary of State for the Home Department what are the guidelines for the conduct of police interviews with convicted prisoners in the furtherance of their investigations into other crimes; what is the legal status of such guidelines; how long they have been in force; and what changes have occurred to previous practices since 1966. 
§ Mr. Maclean
Her Majesty's chief inspector of constabulary issued guidance to the police in January 1987 on the interviewing of convicted prisoners about outstanding crime. The guidance, copies of which are available in the Library, is non-statutory but Her Majesty's inspectorate of constabulary monitors forces' compliance as part of its inspection procedure.
