They are foolish to let him carry on. It was unbelievable that he was ever considered suitable to lead the Conservative party never mind the country. I've had the unfortunate experience of dealing with people like Johnson. There is only one way to deal with them. People who pander to people like him will always be treated with contempt, that includes his fellow MPs and the electorate.
I was listening to an interview with someone who was doing a documentary about Boris.
The man said to Boris that he had said something about a specific subject and Boris immediately denied saying that.
The guy then showed Boris the film clip of him saying exactly that and Boris just laughed and said to the guy that what he had actually said was just as a joke and not to be taken seriously.
And to me, that was a good example of Boris. Saying the first thing that comes into his head, denying ever saying it and then when shown the evidence, passing it off with some excuse or other.
He has repeatedly been proven as unfit for any position of responsibility because he is a showman. An actor who says what he thinks people want to hear. Totally unreliable and totally incompetent and unable to take responsibility for his own mistakes.
