Prince Harry and Meghan Markle to marry in the spring after he proposed earlier this month as the Queen says she is 'delighted' for divorced American actress to join the royal family

Prince Harry and Meghan Markle (pictured together at the Invictus Games in September) have today revealed they are engaged after the Queen gave her grandson permission to marry the star in the week she celebrated her own 70th wedding anniversary. The couple, who revealed they were a couple a year ago after a six-month secret relationship, have chosen to announce they are getting married just before they spend their first proper Christmas together. Meghan (left in Mayfair last Tuesday), who is divorced, could become a princess or alternatively be given the title Duchess of Sussex when she marries the fifth in line to the throne and joins the royal family. Harry, 33, and his American fiancee, 36, have not said where they will hold the ceremony but if they choose the UK most senior royals marry at Westminster Abbey, St Paul's Cathedral or the chapel at Windsor Castle. But they are likely to wait until Prince William and Kate have their third child, which is due in April.
