Its about as meaningful as a headline stating that turkeys have voted against Christmas.
What would anyone expect them to do?
The economic need for more capacity has become critical, it has to happen somewhere. Seagulls will probably vote against one on the Thames estuary but we still have to have one.
Preferably in the Thames estuary, not a half-baked fudge to allow Heathrow to hobble along ever further behind like a three legged dog.
