Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the potential (a) direct and (b) indirect costs to the public purse of the proposed expansion of Heathrow airport.

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 noise, air quality and costs, when making a decision on additional runway capacity.
