Celebrity guests arrived throughout the morning ahead of the midday ceremony
Britain's Prince Harry and the US actress Meghan Markle have become husband and wife.
The royal wedding took place at St George's Chapel, on the grounds of Windsor Castle.
The ceremony began at midday, with a pair of wedding receptions to take place this evening.
The bride was accompanied down the aisle by Prince Charles.
Tens of thousands of people lined the streets in Windsor, hoping to catch a glimpse of the couple before or after the ceremony.
After the wedding, the newly-married couple were brought through the streets of Windsor in a horse-drawn carriage.
The wedding cake is to be served at the Reception. It was designed by Claire Ptak and features elderflower syrup made at The Queen’s residence in Sandringham from the estate’s own elderflower trees, as well as a light sponge cake uniquely formulated for the couple. #royalwedding pic.twitter.com/kt5lE4tEn9— Kensington Palace (@KensingtonRoyal) May 19, 2018

US TV presenter Oprah Winfrey and British actor Idris Elba were among the first of around 600 guests to arrive this morning.
George and Amal Clooney were also in attendance, with David and Victoria Beckham also arriving at the chapel for the wedding ceremony.
Famous musicians in attendance included Elton John and James Blunt.
Several of Ms Markle's former co-stars from the US TV drama Suits also attended.
It was confirmed this morning that Prince Harry, who is sixth in line for the British throne, has gained the title of the Duke of Sussex ahead of the wedding.

In a statement yesterday, the Royal Family said: "Like any couple getting married, Prince Harry and M. Markle have taken a great deal of care in selecting all elements for their service.
