HC Deb 13 June 1968 vol 766 c53W
12. Mr. Ridley

asked the Postmaster-General why the cost of the rental per quarter for a shared telephone line is to be only £3, as against £3 10s. 0d. for an exclusive line.

Mr. Mason

The difference of 10s. between the quarterly rental for a shared line and that for an exclusive line is based on costs.
