HC Deb 09 March 1966 vol 725 c553W
Mr. Forrest

asked the Postmaster-General what arrangements are made in the General Post Office to provide special security for recorded delivery letters and for tracing such letters if they should go astray.

Mr. Joseph Slater

Recorded delivery letters travel with and are given the same security treatment as ordinary mail. If such letters go astray efforts are made to trace them through records at delivery offices and at lost property offices.
