Charles confirmed William is the Prince of Wales since he’s the heir to the throne, with Kate having the Princess of Wales title.

Charles said of William as he addressed the nation for the first time on Friday, “As my heir, William now assumes the Scottish titles, which have meant so much to me. He succeeds me as Duke of Cornwall and takes on the responsibilities for the Duchy of Cornwall, which I have undertaken for more than five decades.

“Today, I am proud to create him Prince of Wales.

“With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire.”

William rushed to Balmoral Thursday afternoon after Buckingham Palace raised concerns about the Queen’s health in a statement.
