HC Deb 19 July 1979 vol 970 c776W
Q41. Mr. Alexander W. Lyon

asked the Prime Minister what progress she has made in constructing an index of living standards to replace the retail price index and whether she proposes to include movements in the social wage within it.

The Prime Minister

We are working on a new tax and price index which would not replace the retail price index, but would supplement it. The precise structure of the new index is still being considered.
