Code when queen dies: ‘London Bridge down’

The UK has a secret plan for Queen Elizabeth II’s death, including a memorial service with the prime minister that should appear “spontaneous” plus preparations to go into crisis mode if London becomes packed with mourners, according to newly revealed documents.

Dubbed “Operation LONDON BRIDGE,” the plan maps out in granular detail what will happen in the first 10 days after the death of the 95-year-old monarch — who is still in good health — Politico reported Friday.

When the queen passes, the prime minister and his cabinet will immediately be told in code, “London

Bridge is down.”

And the government is readying for a crisis, with one memo warning that London could become overwhelmed or “full” by too many people flooding the city to mourn the queen, causing mayhem with public transport, food accessibility, policing and more.

To respond to this possibility, “Operation LONDON BRIDGE” calls for a security operation to be put in place to manage the potential overcrowding. An outline of the plan also shows that, following the prime minister’s official announcement of the queen’s death, a service honoring her will be held at St. Paul’s Cathedral. The PM and some senior ministers are scheduled to attend, but the memorial should reportedly appear “spontaneous,” according to the documents.

Additionally, there are plans for the prime minister and his cabinet to meet the queen’s coffin at St. Pancras station as well as for the queen’s son and heir apparent to the British throne, Prince Charles, to go on a tour of the UK in the days leading up to the funeral as he takes over as king of England.

“Operation LONDON BRIDGE” begins with what is named “D-Day,” where hours after the queen’s death, a “call cascade” will occur where the prime minister, the cabinet secretary, and other senior ministers and officials will be alerted of the queen’s passing by her private secretary, who will state, “London Bridge is down.”

The Privy Council Office, in charge of coordinating government work on behalf of the monarch, also will reportedly be alerted.

The royal household will issue an “official notification” to alert the public, and scripts are in place on how officials should alert others.

For example, the cabinet secretary will e-mail ministers and senior civil servants the following: “Dear colleagues, It is with sadness that I write to inform you of the death of Her Majesty The Queen.”

There are also plans in place for all flags across Whitehall Road to be lowered to half-staff 10 minutes after the news is delivered.
