Decision time at Heathrow
The government has approved the third Heathrow runway, in the interests of jobs and British competitiveness.
The third runway — something airport operator BAA pledged it would not seek if it was granted permission to build Terminal 5 — will open up a sharp political divide, with several Labour MPs, the Conservatives and Liberal Democrats opposed to the idea.
A cross-party parliamentary group is expected to be formed this week to press for the construction of an airport in the Thames estuary, an idea that has the backing of London mayor Boris Johnson, and protest groups like Plane Stupid and Climate Rush say they will hold protests.
