HC Deb 09 June 1964 vol 696 c49W
47. Mr. H. Hynd

asked the Chancellor of the Exchequer whether he is aware that, taking the internal purchasing value of the £ sterling as 20s. in October, 1951, it had declined to 13s. 8d. in January, 1964; and what was the comparable figure at the last available date.

Mr. Maurice Macmillan

Yes, based on the movements in the Index of Retail Prices. The comparable figure for April, 1964, the latest date available, was 13s. 6d.
