Mayor of London Boris Johnson reiterated his support for a new hub airport in the inner estuary, saying expanding Heathrow "would inflict untold misery on hundreds of thousands more Londoners."
It is clear that Gatwick is not being considered as a hub airport, meaning a second runway there would only provide temporary relief to Heathrow.
And that means he has effectively told the Government it has two choices - proceed with the creation of a monstrous Heathrow, on a constrained site that won’t solve our capacity crisis, but would inflict untold misery on hundreds of thousands more Londoners through the din of many more jet engines in parts of the capital and home counties that have not so far experienced it; or proceed with the construction of a new hub in the inner estuary that can be built for the same cost as a four runway Heathrow, and would bring new jobs, homes, and long term competitiveness.
A new airport in the inner estuary is the only credible hub option left, and the only one that would uphold this country’s claim to be the natural financial, commercial and economic capital of Europe.
By keeping it on the table Davies is saying you have a choice - between a damaging u turn or a radical new vision for expansion.
Some believe today's report did not draw firm conclusions in order to avoid a politically divisive issue before the next election.
Expansion of Heathrow and Gatwick Airports are the shortlisted options being considered by a government report into airport expansion.
Heathrow is the third busiest airport in the world in terms of passenger numbers. It carried more than 69 million people in 2011.
