asked the Secretary of State for Employment what was the average industrial wage in 1950, 1955, 1960, 1965, 1970, 1975 and 1979. respectively; what was the average price of a new three-bedroom semi-detached house in (a) London and (b) the West Midlands in the same years; and what proportion of his income a married man with two children under 16 years and an 80 per cent. mortgage paid in tax and national insurance contributions in the same years.

I shall reply to my hon. Friend as soon as possible.
