1) There are rules in the house that govern the behaviour of an MP. The latest revision was issued by no less authority than the squeaker, very recently.
2) Corbyn had to be dragged back to the house to be questioned over his conduct.
3)He then lies to the house about what he said, despite recognized experts in lip reading corroborating the original accusation.
4) When in a hole,why keep digging? His behaviour is neither honest, nor of the standard expected of an MP.
5) To be caught In flagrante delicto on camera, to be viewed by all, is hardly the action of an intelligent man.
