"Much as Boris is not prone to getting really cross, nor using particularly strong language, this was one [time] where he really flipped. At our morning meeting, with a small gang of us, he just launched into a violent attack on Emmanuel Macron. And basically saying: "He’s a four-letter word that begins with 'c'’, he's a weirdo, he's Putin's lickspittle, we need to go studs up on this one" – a rugby term that basically means gloves off - "we need an orgy of frog-bashing, I’m going to have to punch his lights out"... Pretty strong stuff."
