William Arthur Philip Louis was born on June 21, 1982, at the Lindo Wing of St Mary’s Hospital at 9.03pm.

He weighed 7lb 1.5oz and was the first-born son of the King and the late Princess Diana.

Earlier this morning, King Charles posted on the official Royal Family’s social media accounts and wished his son and heir the happiest of birthdays with an adorable throwback picture.

The picture shows Charles beaming while holding baby William on his lap when he was just a few months old.

William’s throwback snap was accompanied by the message: “Happy Birthday to The Prince of Wales!”

The black-and-white image was taken at Kensington Palace in London, on 1 February 1983.

It comes after William, who is president of the FA, was yesterday pictured alongside Denmark’s King Frederick as England drew 1-1 with Denmark in Frankfurt, Germany, in their second match of Euro 2024.

On Wednesday, William joined Kate’s parents, Carole and Michael Middleton at Royal Ascot along with a host of royals including the Queen.
