The King resumed public duties in April after a temporary pause following his cancer diagnosis.

Kensington Palace has posted the image, taken by his mother, Catherine, Princess of Wales.

Prince George, Princess Charlotte and Prince Louis post a Father's Day tribute to Prince William in their first social media post.

In a change of tradition it was taken by a photographer, rather than George's mother, the Princess of Wales.

Princes Louis and George and Princess Charlotte joined other royals for the King's official birthday.

Prince Louis salutes the crowd as he watches the flypast with Prince George and Princess Charlotte.

The Prince and Princess of Wales have been joining the Big Help Out with their three children.

The photograph shows the family of five dressed casually, smiling and holding hands in Norfolk.
