asked the Chancellor of the Exchequer whether he will publish in the Official Report a table showing the real increases in post-tax living standards to 31 March 1979, both in total and for each year since 31 March 1974, taking into account all the Budget changes and any changes in national insurance contributions, assuming for 1978–79 an increase in pre-tax earnings for each person of 10 per cent. and an inflation rate of 8 per cent. to 31 March 1979, and for previous years, assuming the same increase in earnings for each group, as the average increase in earnings that year, for (a) a single person, (b) a married person, (c) a married couple with one child, (d) a married couple with two children, (e) a married couple with three children and (f) a married couple with four children earning in March 1974 £2,000, £3,000, £3,500, £4,000, £5,000, £6,000, £8,000, £10,000, £14,000, £18,000, £20,000 and £25,000, respectively.

I will let the hon. Member have a reply as soon as possible.
