Jennier Arcuri is almost certainly a complete arsehole of a person - not much debate to be had around that, nor should there be here. She is not the issue in this story.
Boris Johnson is a lying, morality free, cheating, bumbling, narcissistic, incompetent, serial abuser of public funds with a proven track record which has led directly to thousands upon thousands of avoidable deaths and the continuing, deliberate impoverishment and disenfranchisement of millions. He is the issue in this particular story, and all it is is yet another piece in a long line of evidence as to his (lack of) character, another stick to beat him with. If only those in a position to do so were willing to take up such a stick.
