HC Deb 13 February 1989 vol 147 c78W
Mr. Allen

To ask the Chancellor of the Exchequer if he will make it his policy to carry out investigations to establish how much revenue is lost each year through tax avoidance and evasion.

Mr. Norman Lamont

The Inland Revenue is already alert for areas where tax is lost through avoidance and evasion. Precise quantification of the total tax involved each year would be impracticable.
