Any bulge of Johnson's would be offensive!
But seriously, you cannot expect this entitled, narcissistic, amoral waste of oxygen to say anything worthy of believing, nor should you expect him to think or talk sensibly, nor to fact check before he opens his mouth and puts his foot in it.
(If it hadn't been for his untrue statement as Foreign Secretary, that Nazanin Zaghari-Ratcliffe was teaching journalists rather than simply taking her daughter on a visit to her parents, then Nazanin's imprisonment would never have occurred.)
Basically Johnson is a dangerous fool. A devious, tricky, expensively educated one, but a fool nonetheless.
