Prince William marked Father's Day with King Charles in a huge break from tradition.
The Prince of Wales took to social media with a throwback photograph of himself and his father, taken before Prince Harry was born.
William captioned the post: "Happy Father’s Day, Pa. W."
The photograph was taken on June 12, 1984, shortly before Prince William's second birthday.

In the picture, a young Prince William could be seen playing football with King Charles, then the Prince of Wales.
William's choice to share this photograph on Father's Day, two hours before a photograph with his own children, marked a huge change in tradition.
It was not until 11am that the Prince of Wales finally shared a picture with Prince George, 10, Princess Charlotte, nine, and Prince Louis, six.
