The expansion of Heathrow Airport has been debated for many years. Here we look at some of the key questions on the latest attempt to build a third runway.
The Government decided to approve the building of a third runway and published a National Policy Statement setting out its position on June 5.
If this is supported by the MPs’ vote, Heathrow will have outline planning permission to expand.
Heathrow is confident there is enough cross-party support, despite opponents such as Foreign Secretary Boris Johnson.

The airport still needs to publish detailed expansion plans, which will be subjected to a public consultation and a planning inquiry.
It hopes to receive final planning permission and begin construction in 2021.
Legal action is likely, with many residents’ and environmental groups opposed to the runway over concerns about noise and emissions.
They are expected to launch a High Court challenge on the grounds that the Government’s decision to support the scheme is unlawful.
A Labour victory in a general election could also cast doubt on the project, given the opposition of shadow chancellor John McDonnell.
The true aircraft noise impacts of an expanded Heathrow means at least 973,000 households, or 2.2million people, would be impacted.

Heathrow has indicated its plan will cost £14 billion.
Airlines express concern that the bill will be passed on to passengers in the form of higher landing charges.
Heathrow insists fees will remain “close to today’s levels”.
Planes could begin using the new runway by the end of 2025.
