Man or mouse, I'm afraid its mouse when it comes to Boris. When a serious situation has transpired with a high ranking minister, the normal procedure would be to sack that minister without further delay, followed up by addressing the nation and condeming the actions of that minister. Boris hasn't got the B**** to do this and never will have,. He does what he normally does, hides away, and lets others face the press, after a time he will allow the odd leak to filter out in the hope of him ever having to explain.
His lapdogs have been covering his backside since the day he was elected. Of course there is always the chance that even Boris knew of Hancock and his tart, so that would make it more difficult for him to conduct himself like an PM should. When you all have your fingers in the pie one way or another and someone gets caught out, the fridge is the only place to hide in the hope it will all go away, it never does, the real s*** in my view is yet to be exposed. Boris now needs to go, or at least hand over the battern.
