British police on Thursday arrested Andrew Mountbatten-Windsor, formerly known as Prince Andrew, over suspicions of misconduct in public office after accusations that he shared confidential information with Jeffrey Epstein while serving as a British trade envoy. The arrest was a stunning blow to the British monarchy, which has been rocked by scandals for decades and is now having to endure the spectacle of having one of its members arrested. The move escalated the long-running crisis for Buckingham Palace over the former prince's ties to Mr. Epstein and allegations of sexual abuse of a young woman.
