Brown lost over immigration at PMQs, but wasn't thumped which is a result for him. He is desperate to tease out a Tory split on the EU referendum, and may be making progress. I notice that when Brown embarked on his usual misleading economic boast (incapacity benefit numbers are dropping about as fast as Venice is sinking), he did not claim to have created 2m new jobs. We now know immigration is to thank for most of this. The Tories should explode the rest of his myths, and leave him with no ammo at all. He seemed more assured today, but Cameron played better to the cameras. And that, of course, is what PMQs is all about.
