A new plan for an airport on the Thames Estuary has been unveiled - with six runways instead of the four originally proposed.
Plans for a Thames Estuary solution to London's airport capacity problems have been dubbed 'Boris Island' after the Mayor expressed his support for them.
The plans have been drawn up by Testrad - the consortium set up by the Mayor to look at Thames Estuary proposals. The new airport would be called 'London Britannia' and sit on a purpose build island off the Isle of Sheppey in Kent.
