HC Deb 28 January 1964 vol 688 c30W
40. Mr. H. Hynd

asked the Chancellor of the Exchequer whether he is aware that taking the internal purchasing value of the £1 sterling as 20s. in October 1951, it had declined to 15s. 11d. in June 1957 and 13s. 9d. in October 1963; and what was the comparable figure for December 1963.

Mr. Maurice Macmillan

Yes, on the basis of the changes in the Index of Retail Prices. The comparable figure for December 1963 was 13s. 9d.
