A moment of drama as thousands file past the queen's coffin. A royal guard collapsed while standing beside Queen Elizabeth II’s coffin. Thankfully, two Scotland Yard officers rush to help the guard. For a moment it appeared that King Charles III was also unsteady on his feet after walking for 40 minutes behind her coffin then standing to attention in the hall. Although the king did not partake in public engagements today, Prince William and Kate Middleton shook hands with wellwishers.
