What Princess Margaret's Relationship With Princess Diana Was Really Like

Princess Margaret stood up for Princess Diana to Queen Elizabeth, with Morton noting in the excerpt of his book published by Town & Country that she told her Diana was "having difficulties adjusting to her role and that she should cut her some slack."

Princess Margaret even stood by Princess Diana after her separation from Prince Charles — at first. The older royal cut off contact after Princess Diana's infamous BBC Panorama tell-all, which left Diana heartbroken. "Diana was devastated by Margaret's hostility," wrote Morton. "From that day forward, Margaret became her fiercest critic and most implacable opponent. She welcomed the queen's decision to ask the couple to divorce as soon as legally possible and supported the move to remove her appellation, Her Royal Highness."

Not even Princess Diana's death moved Princess Margaret. "She said the hysteria was rather like Diana herself... When she died she got everyone to be as hysterical as she was," wrote royal biographer Craig Brown in Ninety-Nine Glimpses of Princess Margaret (via Cheat Sheet).
