The Prince and Princess of Wales shared a new photograph of Prince William with their children, Prince George, Princess Charlotte, and Prince Louis, taken by Kate Middleton, with the caption, 'We love you, Papa. Happy Father's Day,' marking the first time a message from them has been posted on social media. This follows Kate's return to public life at the Trooping the Colour event after a period of cancer treatment. The family was also seen together on the Buckingham Palace balcony. Additionally, Prince William honored his father, King Charles III, with a throwback photo, while King Charles shared a video montage of his own father, Prince Philip.
