You're right, he already knows he'll get away with it, his performance today in the hoc was of a man confident some body else will take the rap. Dame Dick is one of their bum lickers. Grey will already have been promised a Dameship. Am I a cynic or a realist.
I've wondered at times if it isn't lying as such, but multiple personalities - Alexander, Boris. We can see signs of sociopathy, so why not high-functioning schizophrenia? He isn't actually lying at any time, whichever personality is in charge is telling the truth as it sees it... No slight intended to anyone that is neuro diverse and needs medical help to manage their condition(s).
Allegedly, the delay from the Met was due to them investigating themselves and covering up their parties before starting on the government. /s
I honestly couldn't tell you. Certainly a sociopath and heavy narcissistic traits. However he is wired, however he justifies it, however he tries to wriggle out of things, whoever he gets to take the hit, he is still a liar and at some stage it will catch up with him. Hopefully that time is close at hand.
