The Metropolitan Police, emergency services, intelligence agencies, and local authorities are all represented inside the Special Operations Room. There is a gathering for the queen.

Nick Aldworth has spent 36 years in policing and the military and he says it is an enormous room. A senior police officer will make final decisions when teams work in variouspods. The latest updates will be shared at the two main meetings. The tactical advisers will be sitting with the overall commander.

After more than 70 years on the throne, Queen Elizabeth II died on September 8 at the age of 96, and her funeral took place at the SOR. The policing operation is enormous, extraordinary, and the largest one it has ever conducted, according to the Met.

People have paid their respects to the monarch since the queen's coffin arrived in Scotland. The queen flew from Scotland to London. Thousands of people lined the streets and sidewalks to look at the queen's coffin. For days, tens of thousands of people have joined a miles-long queue in London, waiting in line for more than a day to see the queen in state. Millions of people have watched on the internet.

Hundreds of world leaders are expected to join the royal family for the queen's state funeral. There will be a million people in London for the funeral events. Hundreds of police officers were drafted from across the country to London and the town of Windsor for the events. The military staff will be on stand-by.

The police in London will be involved.

During the funeral, which runs for most of the day Monday, the queen's coffin will be moved to the abbey, where a state funeral will take place. Members of the royal family will walk behind the coffin before it is taken to Windsor. There will be a ceremony before the queen is laid to rest.

There is a wall of TVs in the SOR. It is similar to what you would see in a movie. Buckingham Palace is included in the room's video feeds. One of the most surveilled cities in the world is London. There are extra cameras in place for the queen's funeral. There is a backup center 10 miles away if the SOR can't operate.
