Question to the Department for Transport:

To ask the Secretary of State for Transport, what recent comparative assessment he has made of the cost to the public purse of expanding (a) Heathrow and (b) Gatwick airports.

The Government is currently considering the large amount of very detailed analysis contained in the Airports Commission’s final report before taking any decisions on next steps.

The Government will carefully consider all the evidence set out, including that on costs, when making a decision on additional runway capacity.
