Last week, English Prime Minister Boris Johnson boldly declared that he would rather die be dead in a ditch than delay Brexit. Unfortunately for him, the UK parliament accepted the challenge, and promptly dug one for him. The "rebellion bill" requires him to ask for and secure yet another temporary Brexit delay, and it has just received the royal assent. And if he refuses to lie down and shoot himself in it by obeying the law, then it will be the perfect thing to unite the UK's fractured opposition into voting no confidence and appointing a different Prime Minister to carry out parliament's will.
