You think he knows something about the Ukrainian situation which makes it appropriate to pull faces and laugh whilst his Chancellor is talking about Ukrainian children hiding in fear for their lives? And indeed he knows something about that that the Chancellor doesn't know?
OK, I'll buy it, @Hawkins001, tell us what it is that you think he knows. Goodness knows, we'd all like to know something about Ukraine that makes us smile.
