King Charles honored his eldest son, Prince William, on his 42nd birthday as the monarch battles cancer.
The palace, on behalf of King Charles, took to social media and shared a photo of little Prince William with his father to mark the Prince of Wales' 42nd birthday.
Sharing the photo, King Charles says: “Happy birthday to the Prince of Wales!”
In the photo, King Charles is seen holding William and smiling when he was just a few months old.
Royal fans also took the opportunity to wish Prince William a very happy birthday.
One royal fan commented on X, formerly a Twitter handle, “Happy birthday Prince William. Beautiful photo of King Charles with his son.”
Another said: “Happy birthday Prince William.”
“Oh, what a beautiful image. Very cute father and son,” said the third, adding: “Happy 42nd birthday, Prince William!”
This is Prince William's first birthday since his father, King Charles, and his wife Kate Middleton revealed they were battling cancer.
