HC Deb 28 January 1964 vol 688 c31W
Mr. Gresham Cooke

asked the Chancellor of the Exchequer what information he has of the extent to which the cost of living has been reduced following the increase in number of supermarkets in this country during the last 10 years; and if he will give particulars.

Mr. Maurice Macmillan

I think that there is no doubt that the growth of supermarkets has had a favourable effect on the cost of living, but no quantitative estimate is available.
