Caporegime
IDS and Gove wanting out causes me grave concerns. Boris on the other hand is a major coup for the out camp.
I think it would have been a major coup for for In camp if he'd decided to back the UK staying in the EU but tipping his hat for Brexit is much what everyone expected, isn't it? He's also playing down the chances of him taking a major role in the campaign which must be disappointing to the Out camp.
Boris strikes me as a character who could swing the vote if he fully committed to one side or another.
