Wedding of Charles, Prince of Wales, and Lady Diana Spencer

Princess Diana and Prince Charles after their wedding ceremony. There were 3,500 people in the congregation at St Paul's Cathedral. It was held at St Paul's rather than Westminster Abbey because St Paul's offered more seating and permits a longer procession through the streets of London. The service was a traditional Church of England wedding service, presided over by the Most Reverend Robert Runcie, the Archbishop of Canterbury, and the Very Reverend Alan Webster, the Dean of St. Paul's Cathedral. Some say 750 million people watched the ceremony worldwide, and this figure allegedly rose to a billion when the radio audience is added in, however, there are no means of verifying these figures. Two million spectators lined the route of Diana's procession from Clarence House, with 4,000 police and 2,201 military officers to manage the crowds. 29th July 1981.
