I am reporting outside of Buckingham Palace in London, England covering day one after the world received the news of the death of the Queen of England: Queen Elizabeth II.

Many international viewers may not be aware of the official protocol when the Queen dies, but it's known as “London bridge is down.”

This rehearsal has been changed and practiced since the 1960s incase the death of the Queen of England occurs. So here’s what happens on day one.
