HC Deb 24 November 1955 vol 546 c143W
93. Mr. Swingler

asked the Chancellor of the Exchequer what has been the change in the purchasing power of the £ since 28th July, 1950.

Sir E. Boyle

Taking the internal purchasing power of the £ as 20s. in July, 1950, it is estimated that the corresponding figure for October, 1955, is 15s. 10d. This estimate is based on the consumer price index up to 1954, and the Interim Index of Retail Prices thereafter.
