Prince Harry and his best man, his brother Prince William, the Duke of Cambridge, both wore the frockcoat uniform of the Blues and Royals.

Prince Charles walked Markle down the aisle after her father was unable to attend the wedding because of ill health.

The couple exchanged vows and rings in front of 600 guests, including the queen and members of the royal family as well as famous faces such as tennis star Serena Williams, Victoria and David Beckham, Elton John, and George and Amal Clooney, as well as Markle's co-stars from the TV series Suits.

Archbishop of Canterbury Justin Welby pronounced Harry and Meghan husband and wife.

Under a clear blue sky and glorious sunshine, the couple kissed on the steps of St George's Chapel and left Windsor Castle in a horse-drawn carriage for a procession watched by tens of thousands of well-wishers who had crammed into the streets of Windsor hoping for a glimpse of the newlyweds.

Many waved British flags and cheered as the carriage passed by. Royal fans were not disappointed.

Lindsay Hainer, 37, said: "That was absolutely glorious. It really was. It was beautiful, to be part of history. To see that up close like that, she was absolutely radiant, she was sparkling, Harry just looked so happy."

Donna Werner from the United States said: "I just don't know what I'm feeling. Watching the ceremony was unbelievable. She was so beautiful and elegant and regal."

The royal family will pay for the wedding, which includes the service, music, flowers, decorations, and the reception.

Harry and Meghan will carry out their first official engagement as husband and wife on Tuesday.
