HC Deb 16 July 1973 vol 860 c1W
Mr. Arthur Lewis

asked the Minister of Posts and Telecommunications whether he will give, for the longest and most convenient stated period of time, the number of letters and postcards which have been confiscated, returned to sender or failed to be properly delivered because the package contained anti-Common Market stamps.

Sir J. Eden

This is a matter for the Post Office, but I understand that no such records are kept.
