asked the Chancellor of the Exchequer what would be the product of raising income tax 1p in the pound in England, Scotland, Wales and the North-West Region of England.

At 1974–75 income levels the total additional yield from increasing all rates of income tax by 1p is estimated to be about £320 million in a full year. Estimates on the same basis for individual countries and regions are not available but assuming that the proportions for 1974–75 remain as in 1971–72 the figures are as follows:

	£ million
England	275
Scotland	25
Wales	15
North West Region of England	30

NOTE. The North West Region is as defined on page 163 of the Abstract of Regional Statistics 1974 according to the boundaries existing before 1st April 1974.
