HC Deb 11 June 1952 vol 502 c181
4. Mr. Fell

asked the Assistant Postmaster-General when the postmark slogan about underpayment of postage on letters sent abroad is likely to materialise; and what progress has been made with the new system of collecting deficient postage on these letters.

Mr. Gammans

I hope the slogan will be in use in September next. As regards the experimental system of collecting deficient postage, the Post Office has now added postage stamps to over 12,000 underpaid letters and received back from the senders 95 per cent. of the postage made up in this way.
