It is almost two years since Boris Johnson published a document calling for a new airport for London and he has consistently maintained his position since.
In his foreword to the January 2011 publication, Mr Johnson said Heathrow was "not the answer" and that Britain had failed to act on aviation.
He also said that Britain had been "paralysed by the difficulties surrounding aviation rather than recognising the opportunities".
In fine bombastic Boris style he described himself as an aeronautical Bill Cash, unable to let go until he had changed the status quo.
The Mayor of London challenged the Prime Minister today over his demotion of Justine Greening and vowed to fight any expansion to Heathrow.
Jeremy Hunt and Chris Grayling landed promotions as David Cameron sparked minor controversy in reordering his Cabinet for the first time.
