I take it that the Deputy is referring to employee pay-related social insurance contributions, the 1 per cent employment and training levy, the 1.25 per cent health contribution, and domestic service charges under local government legislation. The total yield from these in 1991 is estimated at some £716 million, and to collect this amount in a full year through income tax by increasing the standard rate would mean a standard rate of over 40 per cent. A standard rate of this order would be very difficult to contemplate. As the Deputy will be aware, the standard rate has been reduced from 35 per cent to 29 per cent over the past three budgets, and the Government's aim is to further reduce it to 25 per cent by 1993.
