Heathrow expansion: is MP opposition growing?

The government has reopened the public consultation on plans for a third runway at Heathrow.

While ministers are clear the £18 billion project is still the preferred option, new data raises further question about the environmental impact of expansion, and offers an improved economic case for a second runway at Gatwick instead.

So, with opponents on all sides of the Commons, does the government still have the votes to get the plans off the ground?
