Heathrow

The right hon. Gentleman referred earlier to the Government’s consideration in the 2003 White Paper of the possibility of a Thames estuary airport. Does he accept that the Government did not consider those proposals with anything like the enthusiasm they are now showing for the Heathrow proposals, and that there has not been any serious consideration of a Thames estuary proposal since the Roskill commission in the early 1970s? Will the right hon. Gentleman tell me the name of the engineering consultancy employed by the Government to consider those proposals, for example?
