"[On a clash with anti-Brexit protester, Steve Bray.] He had a go at my weight. This is a man who was quite clearly out of condition. I'm trying to do something about it, but here is a challenge [...] He is a nuisance. And I've got a challenge for him: Meet me in the boxing ring. Let's do three rounds. And if I win, he never protests out there again. And if he wins, I'll go and protest with him."
