asked the Chancellor of the Exchequer if he will revise the figures given in both the appendix 5 of the Treasury and Civil Service Committee report, Session 1981–82 on "The Government's Economic Policy: Autumn Review" and the updated figures given in the answer to the hon. Member for Oldham, West (Mr. Meacher) on 25 October 1982 for those on 75 per cent., 100 per cent., 200 per cent. and 500 per cent. of national average earnings for single, married and married plus two children families, including data on gross earnings, income tax, national insurance contributions, child benefit, net earnings and indirect taxes and net earnings net of indirect taxes in each case on the basis of the most recently available price base and showing the years 1978–79 to 1982–83 and as far back to 1945 as figures will allow and including an estimate for 1983–84 on the basis of announced policy changes and the conventional assumptions incorporated in the latest forecast required under the Industry Act 1975.

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