Labour MP Martin Linton is a vocal opponent of a third runway at Heathrow, yet last night he voted in favour of it. He explains on his website that he didn't really mean to but got confused. I ask you. Still, he is a former Guardian journalist, so we must be forgiving.
But I wonder if his LibDem and Tory opponents will be quite so forgiving when they come to write their next Focus and In Touch leaflets. I think not.
