Mr. Michael McNair-Wilson

asked the Secretary of State for Northern Ireland how many persons are now being held as special category prisoners; and if he will define the meaning of "special category".

Four hundred and twenty on 28th February. The term "special category" refers to prisoners guilty of offences in connection with the civil disturbances whom it is desirable in the public interest to segregate.
