HC Deb 11 May 1966 vol 728 c70W
65. Sir Knox Cunningham

asked the Postmaster-General if he will seek to have the rules laid down in the Convention of the Universal Postal Union altered so as to enable a 15 cents international reply coupon, which in the United States of America costs the same sum as a foreign air mail letter, to be exchanged for a similar air mail letter in the United Kingdom.

Mr. Benn

No. The essence of the International Reply Coupon system lies in its simplicity, enabling each coupon to be used in any country of the Universal Postal Union to cover the postage on an ordinary single-rate letter for abroad.
