HC Deb 02 December 1980 vol 995 c44W
Mr. Austin Mitchell

asked the Chancellor of the Exchequer if he will publish in the Official Report the evidence he has showing that the reductions in the higher rate of tax in June 1979 have increased the wealth of the United Kingdom; and what effect on output he expects these reductions to have in 1981 and 1982.

Mr. Peter Rees

No. While the effects have undoubtedly been beneficial, it is not possible to quantify them accurately.
