The Conservative MP Zac Goldsmith, an opponent to Heathrow expansion, has been making his views clear on the options of the interim report into the issue:
Howard Davies has been very busy this week, nipping & tucking his entirely independent report - on the instructions of Government.
BAA's Colin Matthews tells R4- Heathrow can't be expanded without broad political consensus. There will never be consensus on the 3rd Runway
'Let Britain Fly' wants all Party manifestos to accept the conclusions of the Airports review without even knowing what they are. #democracy
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.
