William and Kate take on Prince, Princess of Wales titles from King Charles

Prince William and Kate will take on the titles of Prince and Princess of Wales following the death of William's grandmother Queen Elizabeth II on Thursday.

William's father King Charles III announced their new titles in a nationally televised speech Friday, his first as king.

"Today, I am proud to create him Prince of Wales, Tywysog Cymru, the country whose title I have been so greatly privileged to bear during so much of my life and duty," Charles said in a prerecorded speech. "With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the centre ground where vital help can be given."

William and Kate, the who have three children, are now the first couple to use the Prince and Princess of Wales titles since they were used by Charles and the late Princess Diana, who divorced in 1996.
