Heathrow has been criticised for the length of time it took to clear tonnes of snow from runways and plane stands after a blizzard on Saturday dumped 5 inches in one hour.
Mr Cameron said: "Even BAA's harshest critics have conceded that given the amount of snow that has fallen, extensive disruption is understandable.
Cleverly put. What he's avoiding saying is that the true picture was actually five inches since Saturday. The second part is simply laughable. This is very British, all the politicians furiously pulling the levers of power only to realise they were connected up years ago and no one has a wiring diagram.
