London: As thousands of tourists arrived here for the Royal wedding on Friday, nearly 1,000 members of Britain's armed forces on Wednesday conducted a dress rehearsal on the streets of London in full ceremonial clothing.

Every aspect of the arrangements for Friday is being practiced to the last detail, including music, flowers, sound systems, drinks, food and security.

Before dawn, personnel of the army, navy and the air force, who will be on duty on the day, wore full ceremonial uniform and left Wellington Barracks in Westminster to take part in the dress rehearsal.

Soldiers lined the route to the Cenotaph, outside the entrance to Downing Street, from where the Royal Air Force personnel lined the road to Horse Guards Parade.

The Westminster Abbey, the ancient venue of the wedding, closed its doors to the public on Tuesday so that preparations could get under way.

According to schedule, on Friday the carriage procession will pass along The Mall, Horse Guards Road, Horse Guards Parade, through Horse Guards Arch, along Whitehall, along the south side of Parliament Square and into Broad Sanctuary.
