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:
The Airports commission said it had not shortlisted any of the Thames Estuary options "because there are too many uncertainties and challenges surrounding them at this stage".
It said it would undertake further study of the Isle of Grain option in the first half of 2014 and said it would:
The commission said it had not shortlisted proposals for expansion at Stansted or Birmingham Airports, but it added:
The Airports Commissions' independent review into airport capacity in the UK has concluded that there is a need for one additional runway to be up and running in the south east by 2030.
The commission found that there is likely to be a demand case for a second additional runway to be operational by 2050.
The Commission said it will now investigate further feasibility studies to look into proposals for new runways in two locations - at Heathrow and Gatwick.
At Gatwick, the group will study the airport's proposals for a new runway to the south of the existing runway.
At Heathrow, two options are on the table: the existing plan for one new 3,500m runway to the northwest, and a new proposals from Heathrow Hub to extend the existing northern runway to at least 6,000m, enabling the the extended runway to operate as two independent runways.
Head of the Airports Commission Howard Davies said the Thames estuary idea, presented by the Mayor of London Boris Johnson, would be considered separately.
Extra airport capacity in the South East is "vital" to the British economy, the London Chambers of Commerce chief executive told Daybreak.
Colin Stanbridge said foreign companies frequently complained about the state of British airports, so much so they were put off investing in the UK:
"We try and get companies to come and invest in London and improve the economy of London. One of the drawbacks of that is, you talk to them and they say, 'yeah but the airports aren't very good.'"
He added links to China could not meet demand because "we haven't got the slots at Heathrow to be able to join up with them."
An interim report from the body tasked with considering the future of UK's airport capacity needs is to be published later this morning.
The findings from the Davies Commission, chaired by former LSE director Howard Davies, will be published on the Commission's website at 7am this morning.
The construction of a third and fourth runway at Heathrow has been suggested as one possible option for airport expansion, as well as the possibility of an airport at the Thames Estuary.

Gatwick airport should be encouraged to build a "robust business case" for a second runway at the West Sussex airport, the transport select committee has said.
They also recommended further expansions to Heathrow airport.
