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."
