Boris Johnson is calling on the Government to build a new airport in the Thames Estuary.

The London Britannia Airport (Boris Island) includes four floating runways tethered to the sea bed.

Dismissed as a vanity project by opponents, Boris Johnson remains committed to a new hub airport in the Thames Estuary as a way of easing pressure on Heathrow.
