Prince Harry to Marry Girlfriend Meghan Markle Next Year
Prince Harry says he is "thrilled" after announcing he is to marry US actress girlfriend Meghan Markle.
The fifth in line to the throne will marry Ms Markle in spring 2018.
The couple, who have been dating since the summer of 2016, smiled as they posed for photographs outside Kensington Palace in London, where they will live.
Prince Harry said it had been a romantic proposal, while Ms Markle said she was "so very happy, thank you".
Ms Markle, wearing a white belted coat, held Harry's hand as they appeared briefly for the press at the palace's Sunken Garden, and showed off her diamond engagement ring.
Asked by a reporter when he knew Suits star Ms Markle "was the one", Prince Harry said: "The very first time we met".
A TV interview the couple are giving to the BBC's Mishal Husain will be broadcast at 18:00 GMT.
Kensington Palace said Ms Markle's engagement ring was designed by Prince Harry and features two diamonds which belonged to his late mother, Diana, Princess of Wales.
At the centre of the ring is a diamond from Botswana, a country the couple has spent time together over the last year and a half. The band is made from gold.
