It seems that a particularly odious bully, who was abusing his position of trust, has received his just desserts.

He'll certainly lose weight, let's put it that way. Maybe he'll be joined by some MPs in due course?
On a side note, can anyone guess in which county a practising coroner has a conviction for perverting the course of justice?
