HC Deb 19 July 1979 vol 970 c787W
Mr. Craigen

asked the Secretary of State for Trade what are the latest estimates on the cost to public funds of a third London airport.

Mr. Tebbit

The costs of providing a third London airport are likely to vary according to the site. No estimates are available at present, but I expect the study group on South-East airports to provide an analysis of the costs when it submits its report in the autumn.
