Boris Johnson has reiterated his belief that London and the UK need to build a new airport in order to "remain competitive" against other ambitious cities.
The Mayor of London said a new airport should be located away from the Heathrow area which currently "blights the lives of hundreds of thousands of Londoners".
He suggested the area, with good transport links and infrastructure, could be used to generate 100,000 new homes.
Mr Johnson said: "Ambitious cities all over the world are already stealing a march on us and putting themselves in a position to eat London's breakfast, lunch and dinner by constructing mega airports that plug them directly into the global supply chains that we need to be part of.
"For London and the wider UK to remain competitive we have to build an airport capable of emulating that scale of growth."
