The Airports Commission has recommended that a new runway is built at Heathrow airport in West London.
The commission said that a new runway at Heathrow is the best option to add "urgently required routes to new markets".

A comprehensive package of measures should be introduced, including a ban on night flights, a noise authority and a levy to fund compensation schemes, the commission also said.
The Government is not expected to take any immediate action on the report and is likely to announce that ministers will study the recommendation.
