The Duke and Duchess of Cambridge are celebrating their 10th wedding anniversary this week, and to mark the occasion the BBC will broadcast a special documentary.

Royal Wedding: A Day to Remember, will be shown on Friday, a decade on from their wedding.

The couple married on April 29, 2011 at Westminster Abbey, after they met as students at the University of St Andrews in 2001.

The hour-long documentary will look back at the future king and queen's wedding day and features people involved in the planning of the event, as well as a number of guests.

Former Archbishop of Canterbury Rowan Williams, who married the pair, is one of the contributors to the documentary, as well as composer John Ritter, florist Shane Connolly and former England rugby coach Sir Clive Woodward, who all contributed to the planning of, or attended, the couple's nuptials.

Former UK prime minister David Cameron is also one of the voices in the documentary.

“You could just see in their faces the excitement of the day, but in his face, the pride that he’d come to this point, this position, in which he’s getting married to somebody that he truly loves,” said the charity Centrepoint's chief executive Seyi Obakin, who was there for the couple's big day.

In 2011, the wedding was watched by 17.6 million people in the UK and two billion worldwide.

During the event, Kate wore a custom gown by Alexander McQueen for the royal ceremony, which was conducted by the Archbishop of Canterbury.

The highly anticipated big day was attended by members of the royal family, including Queen Elizabeth II, with Prince Harry acting as best man.

The couple have since welcomed three children: Princes George and Louis, and Princess Charlotte.
