This year's Commonwealth Day service at Westminster Abbey was arguably the most high-profile gathering of senior royals since the arrest of Andrew Mountbatten-Windsor. It's no surprise that all eyes were on the likes of Princess Anne, Prince William and Catherine, Princess of Wales as they joined the King and Queen on 9th March.
Every detail of the annual occasion, which brings together representatives from the 56 nations that make up the Commonwealth, was keenly observed. This includes Kate's brilliant interaction with her aunt-in-law the Princess Royal.
