London Mayor Boris Johnson defended his proposal for a new hub airport in the Thames Estuary east of London, after an influential House of Commons committee said the idea should be ditched in favour of a third runway at Heathrow.
In a report published on Friday, the Commons Transport Committee said that the “Boris Island” option would be hugely expensive, could harm estuary wildlife and would also mean the closure of Heathrow.
Instead, the MPs said that an extra runway at Heathrow was necessary and also suggested that a fourth might have merit if the two new runways were located to the west of the current site. The current two-runway airport was “not adequate for the needs of the UK” and expansion of Heathrow was “long overdue”, they said.
But Mr Johnson said that a four-runway Heathrow would subject Londoners to levels of noise pollution “they haven’t yet dream of” whilst also disputing the MPs cost findings.
