If Harry and Meghan (TM) knew their Shakespeare better, they might be a lot more careful. Remember George, Duke of Clarence: he had a pretty good claim to the throne, but he would keep shooting off his mouth: they wound up drowning him in a barrel of wine.
This pair of (ahem!) royal jidrools has had three more years in which to convince the British public that they absolutely positively do not need a royal family anymore. If Harry and Meghan (TM) can put you off royalty, no one can.
