HC Deb 11 June 1968 vol 766 c16W
Mr. Ryan

asked the Chancellor of the Exchequer, taking 1952 as a base year, what was the value of the £ on 1st January, 1962, and 1st January, 1968, respectively.

Mr. Harold Lever

Taking the internal purchasing power of the £ sterling as 20s. in 1952, its value in January, 1962, and January, 1968 are estimated at 15s. 10d. and 13s. 3d., respectively.

These estimates are 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 periods.
