Prince Louis has been photographed barefoot, with a beaming smile - and ready for a game of beach cricket - in a series of images taken to mark his fourth birthday.
The young royal has been snapped by the Duchess of Cambridge enjoying himself in the dunes of Norfolk, which are a popular attraction for tourists who flock to the county each summer.
Four pictures have been released of Louis who turns four today and reveal William and Kate’s youngest child is growing up fast.
