Boris Johnson today renewed his call for a massive airport in the Thames Estuary ... a development that would transform Kent's economy but sentence thousands of people to living under one of the world's busiest flightpaths.
In a stinging attack on Government aviation policy, the London mayor said an estuary airport - or major expansion of Stansted - were the only logical options. He described Government resistance as "blind" and "complacent".
But his speech at London's City Hall triggered attacks from Tory colleagues and prompted the question: how much is this about airport capacity ... and how much is it about Boris's political ambitions? Tom Savvides reports.
