Princess Diana's sister, Lady Sarah McCorquodale, made a rare public appearance to support her nephew, Prince William, at the Sovereign's Parade at the Royal Air Force (RAF) College in Cranwell, Lincolnshire. This event marked William's return to the place where he earned his wings in 2008, and his speech acknowledged both the graduates and their families' support. This appearance follows a period of family solidarity, including a recent Spencer family funeral attended by both William and Harry. Lady Sarah, who introduced Diana to Charles, remains a key figure in maintaining relationships within the family, despite William and Harry's strained relationship. Her presence underscores the continuing influence and legacy of Princess Diana within the royal family.
