§ 61. Mr. Maplesasked the Chancellor of the Exchequer what has been the increase in real terms in the yield from higher rate income tax between 1978–79 and 1985–86.
§ Mr. Norman LamontThe total tax liability resulting from the difference between the higher rates of income tax and the basic rate rose by about 30 per cent. in real terms between 1978–79 and 1985–86.
