Britain's Prince William and his wife Kate published photographs of their youngest child Louis on their official social media accounts to mark his fourth birthday.
The photographs of Louis, who turns four on Saturday, were taken by Kate in Norfolk, East England, and show him smiling, holding a cricket ball and running along a beach.
Louis is a great-grandson of Queen Elizabeth II, and fifth in line to the throne, behind his grandfather Charles, father William and siblings George and Charlotte.
