HC Deb 10 March 1988 vol 129 c317W
88. Mr. David Martin

To ask the Chancellor of the Exchequer what studies he has made of the relationships between levels of income tax and resultant revenue.

Mr. Norman Lamont

Many factors influence the yield of income tax. Since 1985–86 the basic rate of income tax has been reduced from 30p to 27p, but growth in the economy and other developments have led to the yield of income tax increasing in both nominal and real terms.
