HC Deb 16 November 1981 vol 13 cc29-30W
Mr. Denis Howell

asked the Secretary of State for Industry what information he has as to the number of private lines for alarm systems supplied by the Post Office or British Telecom which were in use in each year from 1978.

Mr. Wakeham

British Telecom, whose responsibility this is, tells me that the information is not available.
