Several ministers will soon join Foreign Secretary Boris Johnson and Education Secretary Justine Greening in publicly condemning the Government's plans to build a third runway at Heathrow Airport, ITV News has learned.
ITV News Deputy Political Editor Chris Ship tweeted:
I'm told more ministers will join Boris and Justine in opposing #Heathrow in the coming days. Not Cabinet - but ministerial level
Tory MPs are taking lumps out of each other on Heathrow, grammar schools and - above all - the true meaning of Brexit.
Environmentalist Goldsmith called the move "catastrophic" - and announced he will now stand as an independent in protest.
The expansion of the London airport will affect the whole of the UK, with more domestic routes, while impacting air fares and house prices.
