The British royals have published a picture of Prince William and his children for Father’s Day, which is celebrated in Great Britain and many other countries on Sunday. The second in line to the British throne, who celebrates his 40th birthday next Tuesday, is in high spirits with Prince George (8), Princess Charlotte (7) and Prince Louis (4) in the Jordanian desert.

All three children have their mouths wide open with delight. William carries his youngest son on his shoulders and smiles contentedly at the camera. “Wishing a Happy Father’s Day to fathers and grandfathers around the world today!” wrote the Kensington Palace Twitter account.

Buckingham Palace published more photos on a separate Twitter account, including Prince Charles (73) with his two sons William and Harry (37) when they were young. As the British tabloid “Daily Mail” reported, citing insider circles, the relationship between the once inseparable brothers is still significantly disturbed. William mourns the loss of the close brotherly bond, but at the same time he is “very, very angry” at Harry’s behavior, the paper said.
