What Is Next? As Prince Charles Becomes King Charles III and Prince William Becomes the New Prince of Wales

Prince William is now heir to the throne of the United Kingdom after Prince Charles's accession following the death of Queen Elizabeth II.

The 40-year-old Duke of Cambridge is expected to become the new Prince of Wales, with his wife Kate Middleton taking on the new title of the Princess of Wales.

William is the oldest royals among the top eight in line, and is followed by his three children Prince George, nine, Princess Charlotte, seven, and Prince Louis, four.

Following the Cambridges are Prince Harry, his children Archie and Lilibet, and then Prince Andrew and his two daughters Princesses Beatrice and Eugenie of York.

William has become a hugely popular member of the Royal Family in recent years, with his wedding to Kate in April 2011 watched by an estimated two billion people.

The couple's down-to-earth nature and regular foreign trips have helped them engage with global communities, including one in Pakistan in October 2019.

William has also become more involved in royal matters, with a notable intervention after Prince Andrew's interview about his friendship with paedophile Jeffrey Epstein.
