The UK House of Commons voted on approving Heathrow expansion, or at least, that's how it is described in the media. At closer scrutiny, however, it looks like the vote is just about a government policy statement approving expansion in principle. It is supposed to be privately funded (see also this question).
Does the vote relate to a a costed privately funded planning application? Or can, in the event of parliamentary approval, Heathrow expansion still be cancelled or postponed if owners come back stating that they are unable to acquire the necessary financing?
