During a visit to a center in Manchester, 11-year-old Tyrell Richards-Walker asked Prince William how much money he had in his bank account. The prince answered, "I don't know, I can't remember." It is estimated that Prince William's fortune is around £1 billion, after inheriting properties from his father. The British royal family has a net worth of over £20 billion. In a separate incident, Prince William and Kate Middleton shared three photos of Prince Charles on their Instagram account to mark his birthday. One photo showed young William and his father skiing, another was of Prince Charles alone, and the third featured the Duke and Duchess of Cambridge with Prince George, Princess Charlotte, and Prince Louis on Trooping the Colour day. The picture was captioned, "Wishing a very happy birthday to The Prince of Wales!"
