We just thought we would have a quick watch of the live stream of the people going to see the coffin. About 10 minutes ago they brought in duplicates of all the guards, swapped them all over and the original ones left. Ok so that was clearly the changing of the guard. But now they have just done it again. Some banging and then in walked another set of duplicates and they've swapped them over again. The queues have to stand still while it happens then they just walk on by once it's finished.
Why would they change the guard over twice in 10 minutes?
