Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will take steps to ensure that all proposals for a third runway at Heathrow Airport will avoid unnecessary cost and delay, including options that would require construction over the M25.

The Government is clear that any expansion at Heathrow must be delivered in a way that minimises cost for passengers and customers. The scheme will be privately financed, including both the core runway infrastructure and any related improvements to surface access. Promoters are expected to engage constructively with relevant authorities, such as National Highways, to develop solutions that support the wider transport network and minimise disruption.
