Prince Harry and Meghan Markle have become husband and wife in a moving ceremony at Windsor Castle.

An emotional-looking prince and his smiling bride exchanged vows and rings before the Queen and 600 guests at St George's Chapel.

Ms Markle, wearing a white boat-neck dress by British designer Clare Waight Keller, was walked down the aisle by Prince Charles.

At the altar, Prince Harry told her: "You look amazing."

After the service the couple - who will now be known as the Duke and Duchess of Sussex - kissed in front of cheering well-wishers on the steps of the chapel.

Thousands of members of the public turned out in bright sunshine to see them driven around Windsor in a horse-drawn carriage.

Later, Prince Harry drove the couple to their reception in a silver blue Jaguar, with a registration plate that referenced the date - E190518.

Guests at the wedding included Oprah Winfrey, George and Amal Clooney, David and Victoria Beckham and Sir Elton John, who later performed at the wedding reception.
