Britain’s Prince William has gone some way to restoring the royal family’s academic reputation by earning a 2:1 honours degree in geography from St Andrews University in Scotland.

The result, announced on Saturday by William’s press office, means he has overhauled his father, heir-to-the-throne Prince Charles, who managed a lower second class honours degree in history from his time at Trinity College, Cambridge.

William’s younger brother Harry decided not to study at university after leaving school with two A-levels in geography and art and is now training to be an army officer.

William is expected to join around 1,400 other students for a graduation ceremony at St Andrews later this month. The 22-year-old celebrated his degree result by taking part in the annual Trooping the Colour ceremony in London to mark his grandmother Queen Elizabeth’s official birthday.
