I'd love to see Cameron snuggle up to the Green lobby and tell the jobs and businesses this would generate to p*** off as he attempts to get the UK working again. A way will be found to "180 backtrack".
The piddling number of jobs lost will be nothing to the votes Labour will lose over Heathrow expansion. Millions of people will be affected by it, many south Londoners who have no access to the airport due to the total lack of public transport.
