§ Mr. Marlowasked the Chancellor of the Exchequer what was the effective percentage rate of stoppages, namely, income tax plus national insurance, on the taxable income, after allowances, of a married householder with an average mortgage commitment earning: £4,000, £4,500, £5,000, £5,500, £6,000, £6,500, £7,000, £7,500, £8,000, £8,500, £9,000, £9,500, £10,000, £10,500, £11,000, £11,500, and £12,000 gross income as at 1 January 1980; what will be the effective percentage rate of stoppage in each case at 1 January 1981 where each earnings figure has been inflated by the rate of increase in average earnings and the quotient represents taxable income and assumes for calculation purposes only that taxable income is a similar proportion of gross income as previously; and what is the difference between the two figures.
§ Mr. Peter ReesI shall let my hon. Friend have a reply as soon as possible.
