Watch shocking moment a royal guard collapses at foot of Queen's coffin

TV viewers were left in shock when live footage of the Queen lying in state showed one of the royal guards watching over Her late Majesty’s coffin suddenly collapse.

The guard was standing at the foot of the late monarch’s casket when he suddenly fell to the floor.

The incident happened at around 12:30am, the black-clad guard was holding a ceremonial staff when he appeared to faint, with nearby officials quickly rushing to his aid.

As he was tended to, the live vision quickly faded to exterior, night-time vision of the building. Over an hour later, the broadcast had still not returned to the scene inside the hall.
