I’m the first to point out other’s mistakes. So I’m happy to print that John Denham, innovations secretary, is in favour of the third runway at Heathrow – contrary to a report I did on ft.com yesterday. Apparently he has no concerns whatsoever about the scheme and its impact on climate change etc.

That still leaves a substantial number of cabinet ministers with forebodings about the project, given its likely impact on greenhouse gas emissions (and local noise and pollution).
