HC Deb 03 July 1969 vol 786 c120W
41. Mr. Montgomery

asked the Postmaster-General at what time the cheap rate for telephone calls begins at weekends.

Mr. Joseph Slater

At 6 p.m. on Fridays until 8 a.m. on Mondays, although on Saturdays between 8 a.m. and 6 p.m. a higher rate applies which is still, however, ⅓ lower than the weekday rate.
