London Mayor Boris Johnson will risk the wrath of Prime Minister David Cameron today by highlighting "unnecessary" delays in formulating aviation policy.
Mr Johnson is expected to repeat calls for his Thames Estuary airport scheme, dubbed "Boris island".
In a speech to business leaders, the mayor is likely to be critical of the timescale of the recently announced, Whitehall-commissioned independent report on aviation being headed by former Financial Services Authority chief Sir Howard Davies.
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.
