There was a hustings this week. David Lammy made clear he was not convinced by his fellow Labour MP Sadiq Khan sudden claim to be opposed to the third runway at Heathrow. (About 1 hr 23 mins in.)

“We should not play politics with this issue. Sadiq was for Heathrow expansion in 2008. He was for it when he was Transport Secretary in 2009. He was for it on the Sunday Politics just a few months ago. Zac Goldsmith announces he running and suddenly Sadiq is against it.

“I think it’s important to be straight with people. To be honest with people. And not be playing the same Ed Miliband politics that got us nowhere.”
