HC Deb 20 February 1952 vol 496 c19W
10. Captain Ryder

asked the Assistant Postmaster-General whether his attention has been called to the fact that the notice of termination of agreement recently sent to all telephone subscribers did not appear to conform with the usual regulations for registered letters; and whether it is no longer necessary under his regulations for registered letters to be sealed.

Mr. Gammans

The notices in question were posted as printed paper packets: such packets, unsealed, are admissible to the registration service.
