§ Mr. Silvesterasked the Chancellor of the Exchequer (1) what would be the cost of introducing an income tax rate of 15 per cent. to apply to half the present 30 per cent. tax rate band, leaving other tax rates undisturbed;
(2) what changes would be necessary to higher rate bands to ensure that no tax benefit accrues to higher rate taxpayers if a lower rate band is introduced at 15 per cent. to apply to half the present 30 per cent. tax-rate band.
