HC Deb 02 June 1964 vol 695 c141W
Mr. Brockway

asked the Postmaster-General if he will issue instructions that letters insufficiently or wrongly addressed shall be sealed when returned to the sender.

Mr. Mawby

Undeliverable letters returned to the sender are sent in sealed covers; and I do not think re-sealing the letters themselves would achieve the purpose the hon. Member has in mind. I am explaining the position in more detail to the hon. Member in my reply to the letter which he has sent to me.
