Heathrow: First it was celebrities buying plots of land on the third runway site (see below).
But the Tories are throwing a bigger spanner in the works: they vow to pull the plug on the project if they get into government – this was said categorically by shadow transport secretary Theresa Villiers on BBC Radio 4’s Today programme. 
Surely this must be a bigger threat than the likes of Emma Thomson and Zac Goldsmith buying parcels of land in fields near the Sipson – the village earmarked for bulldozing to make way for the runway.
I expect most political pundits would say all bets are off at the moment as to who would win the next election and when that will be. But they’d probably say the Tories have a fair chance of winning.
This raises a whole bunch of interesting questions for the project. What will happen to the massive amount of commercial contracts signed off by then if the projects already underway?
Participating companies would presumably already invested millions. Is this going to put firms off bidding?
What if compulsory purchase orders for the site have already been completed?
And does this mean they will give stronger support to a new estuary airport? – as proposed by London Mayor Boris Johnson
