HC Deb 05 May 1966 vol 727 c156W
Sir Knox Cunningham

asked the Chancellor of the Exchequer whether, taking the value of the pound as 20 shillings in 1946, he will state its comparable value today.

Mr. MacDermot

Taking the purchasing power of the £ sterling as 20s. in 1946, its value in March, 1966, the latest date for which information is available, is estimated at 10s. This estimate is based on changes in the Consumer Price Index for calendar years adjusted by movements in the Retail Price Index for the months at the end of the period.
