HC Deb 28 March 1983 vol 40 c50W
Mr. Straw

asked the Secretary of State for Employment if he will list in the Official Report details of changes in the construction of the retail price index since May 1979, together with an explanation of the reasons for the changes.

Mr. Gummer

No changes have been made in the basic system of construction of the retail prices index. However, as part of this system, the index "basket" is brought up to date each January in line with changes in household spending on goods and services.
