Boris Johnson has renewed his attack on proposals to expand Heathrow airport, calling the plans "barbarically contemptuous of the rights of the population".
The Mayor of London was writing in the Daily Telegraph as business chiefs published a report urging politicians to make sure work on airport expansion has "spades on the ground" by 2020.
Mr Johnson, who favours a new hub in the Thames Estuary, claimed building extra runways at Heathrow was "desperately short-sighted" and would cause congestion and "medical problems associated with pollution".
