asked the Secretary of State for Prices and Consumer Protection if he will refer to the Director General of Fair Trading for investigation the practice of the Post Office to supply postage stamps from stamp machines of value less than the coins inserted in these machines; and if he will make a statement.

From the additional information which the hon. Member has submitted to me, it appears that the problem relates to a single defective stamp vending machine and not a Post Office practice. This is a matter which should be taken up with the Post Office.
