What plans are in place for the Queen’s death?
Although plans have been in place for decades in a process dubbed “Operation London Bridge”, a series of documents obtained by political news outlet Politico details the specifics of the protocols when the monarch dies.
The security plan is outlined in full, detailing everything from how news of the monarch’s death will be shared to the public to how quickly Prince Charles will ascend the throne.
It also includes details on what will happen during the 10 days following the Queen’s death, including where her coffin will go, how Prince Charles will spend his first few days as King and how the prime minister will publicly address the news.
The day that the Queen dies will be referred to as D-Day, with every day afterwards referred to as D-Day+1 and D-Day+2 and so on, going up to and including D-Day+10.
The report claimed that a “call cascade” will take place hours after the monarch’s death in order to inform the prime minister, the cabinet secretary, and several senior ministers and government officials of the news.
The prime minister will be told by the Queen’s private secretary, as will the Privy Council Office, with permanent departmental secretaries to be given a script in order to inform other government ministers.
This will reportedly read: “We have just been informed of the death of Her Majesty The Queen,” and ministers will also be told that “discretion is required.”
The cabinet secretary will then send an email to senior civil servants.
The public will be told by an “official notification” which will be delivered by the royal household, according to the documents.
