Question to the Department for Transport:

To ask the Secretary of State for Transport, what financial assessment he has made of the effect on the Barnett Consequentials for Wales of the Transport for London funding required to service a third runway in Heathrow.

The Government has made no such assessment as we are clear that the costs for works on the transport network which are physically needed to enable the Heathrow Northwest Runway scheme to operate will be privately financed.

Where the costs are for transport works that are not solely required to deliver airport capacity and have a wider range of beneficiaries, the Government, along with relevant stakeholders, will consider the need for a public funding contribution alongside an appropriate contribution from the airport on a case by case basis. Such Government costs would be subject to the Barnett formula.

Additionally, Transport for London (TfL) spending is a matter for the Mayor of London. Funding for TfL from the Department for Transport has been subject to the Barnett Formula in the usual way, as set out in the Statement of Funding Policy.
