Prince Harry and Meghan Markle's new titles revealed

The Queen has announced the royal titles she will bestow on Prince Harry and Meghan Markle after their wedding.

Previous speculation has been proven correct and the happy couple will indeed be known as the Duke and Duchess of Sussex following their wedding in St George’s Chapel at Windsor at midday local time on Saturday.

Queen Elizabeth II grants every royal union a set of new monikers and the title of Duke of Sussex is vacant for Prince Harry to assume.

Queen announces Meghan Markle and Prince Harry’s official royal titles.

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

This means Ms Markle will be the first woman ever to hold the title, HRH The Duchess of Sussex.
