Heathrow Airport: Construction

Question: To ask the Secretary of State for Transport, if she will commission an independent financial review of the feasibility of Heathrow expansion.

Answer: The Government recognises the importance of ensuring that any scheme for Heathrow expansion is deliverable and affordable. Last year, the Government undertook a comparative assessment of the proposals, on its individual merits against the published criteria, which included financial considerations. Since this is a private sector project, it is for the potential promoters to develop and finance expansion proposals, and to demonstrate that any scheme is financially viable.
