70. Dr. Bennett
asked the Chancellor of the Exchequer what was the purchasing power of the£sterling on 18th November, 1968, on 17th November, 1967 and on 1st October, 1964.
§ Mr. Harold Lever
Taking the internal purchasing power of the£sterling as 20s. in October, 1964, its values in November, 1967 and October, 1968, the latest date for which information is available, are estimated at 18s. 1d. and 17s. 2d. respectively.
These estimates are based on changes in the consumer price index between the calendar year 1964 and 1967 adjusted by movements in the retail price index for the months at the beginning and end of the periods.
