HC Deb 04 July 1968 vol 767 c262W
59. Mr. Arthur Lewis

asked the Postmaster General why a 4d. stamped letter posted in the House of Commons at 7 p.m. on a mid-week evening, addressed to London, E.C.I, details of which have been supplied to him, was not delivered until the afternoon of the following day, instead of the first morning delivery.

Mr. Joseph Slater

As the envelope is not available I am sorry I have been unable to find any reason.
