HC Deb 02 February 1982 vol 17 c91W
Mr. Nicholas Winterton

asked the Secretary of State for Transport if he will estimate the approximate net cost to the Government of public sector investment expenditure on motorways after savings on unemployment benefit and the drawback of taxation from higher incomes of employed persons are taken into account; and how this compares with the net cost of public sector investment expenditure on the railways system.

Mr. Kenneth Clarke

Such estimates cannot be made without making too many questionable assumptions.
