HC Deb 25 May 1972 vol 837 c482W
Miss Devlin

asked the Chancellor of the Exchequer what sum is now of equivalent value to £1 in 1923.

Mr. Nott

It is estimated that £4.23 would have had the same purchasing power in April, 1972 (the latest date for which information is available) as £1 sterling in 1923. This estimate is based on changes in the Cost of Living Index up to 1938, linked to the Consumer Price Index for calendar years thereafter with a final adjustment on the basis of the General Index of Retail Prices for the months at the end of the period.
