Harry, Meghan will be Duke and Duchess of Sussex: palace

Prince Harry and Meghan Markle will be known as the Duke and Duchess of Sussex after their wedding today, Kensington Palace announced, making her the first woman entitled to use the title.

"The Queen has today been pleased to confer a Dukedom on Prince Henry of Wales. His titles will be Duke of Sussex, Earl of Dumbarton and Baron Kilkeel," the Kingston Palace said in a statement.

"Prince Harry thus becomes His Royal Highness The Duke of Sussex, and Meghan Markle on marriage will become Her Royal Highness The Duchess of Sussex," it said.

Millions of people around the world are tuning in to watch Harry's marriage to Markle at St George's Chapel in Windsor Castle today.

The bride will arrive with her mother, Doria Ragland, and then be walked down the aisle by Harry's father, Prince Charles, to exchange her wedding vows at the altar.

By tradition, male members of the Royal family receive a title from the monarch on their wedding day, and the vacant title Duke of Sussex has always been regarded as the most likely choice for the Prince, The Telegraph reported.

It would mean that Markle will be the first woman entitled to use the title 'Her Royal Highness The Duchess of Sussex', the report said.

The only previous Duke of Sussex was married twice, but neither of his marriages was approved by his father, George III, meaning they were considered unlawful.
