HC Deb 31 January 1967 vol 740 c36W
34. Mr. Longden

asked the Chancellor of the Exchequer why the 6d. National Savings stamp has been abolished so that the lowest value of such stamps is now two shillings.

Mr. Diamond

To bring the figure into line with current practice, to avoid substantial wasteful expenditure and to assist those who voluntarily give their time to promoting children's savings and to whom I would once again wish to convey the nation's thanks.
