Traffic was brought to a standstill this morning as military personnel went through a full dress rehearsal for Friday's royal wedding.
Up to a thousand members of the military were involved, including the Army, Navy and RAF, and saw roads closed across central London.
The day began at about 2am for those involved, with forces leaving Westminster's Wellington Barracks shortly before 5am to begin their way along the route.
First to arrive at the abbey were two of the royal fleet cars - Rolls-Royces which arrived at about 4.50am.
Shortly after 5am the action began. It was audible only at first as the sounds of orders being barked out emerged from the final stretch of the route running down from the Houses of Parliament to the abbey.
Several companies of the Royal Navy lined the conclusion of the route, preceded by the Army lining Parliament Street.
When the couple leave the abbey as man and wife, two groups of 12 military personnel will line their route as they make their way to their horse-drawn coach.The tribute is traditionally performed at many military weddings.
