Surely the point is, we British are very different from our European cousins. They simply don't "get" us - our quirkiness and our sense of humour. I'm not saying our fundamental values aren't similar, but our country needs someone a bit more charismatic and transformational.
Boris would be fine for me. He communicates (in several languages as has been said), in addition he is a man of action not just words and if an idea don't hold water, (his infamous Wasserwerfer), he is happy to laugh at himself and move onto the next thing. "Stable" may not be his favourite way of governing, but up against the likes of Trump he would be able to spring surprises and give as good as he gets. Boris transcends traditional politics and his appeal to Joe Bloggs in the East End of London equalled his popularity to the toffs and dolls of Knightsbridge, therefore he can employ this like-ability/charm around the world.
My DH is a kind of Boris and though he is selfish, puffed up and infuriates some, he does get the job done and underneath is prepared to apologise when he messes up. Maybe the Conservative party should have chosen Boris first time round. I'm sure if he does become leader he won't entertain all this backwards and forwards nonsense we see currently and he would be a forceful, effective figure for the Opposition.
