Operation London Bridge: the 10-day procedure that began with Queen Elizabeth II's death

Digital Desk: After spending more than 70 years in the British monarchy, Queen Elizabeth II passed away on Thursday at the age of 96, with members of the royal family by her side. Her death triggered a precise plan established in the 1960s to be carried out in the case of the monarch's death. The highly detailed plan outlines the steps that must be taken immediately after her death and that culminate with her funeral ten days later.

The plan to deal with the death of the head of state of the United Kingdom was dubbed Operation London Bridge, and it was originally published by The Guardian in 2017, and then by Politico in 2021.

According to The Guardian, the London Bridge plan factored in the eventuality of her passing at Balmoral. The part of the plan for her death at her favourite castle in Scotland was codenamed ‘Operation Unicorn’.

These protocols actually serve as a thorough outline for the funeral procession and other important logistical tasks.

The day after her death is designated as D+1, while the day of her funeral is designated as D+10 (D-day plus 10 days). Following the transmission of a condolence message, the British parliament will adjourn for these ten days. 

According to the plan, after informing the British Prime Minister, information about the Queen's death had been sent to other governments where she was the head of state and then to 38 other Commonwealth nations.

Additionally, Prince Charles will immediately succeed the late Queen as king and head of state for all 14 Commonwealth realms. A formal proclamation, though, won't be made until the day following the Queen's death. According to the BBC, this will take place in front of the Accession Council, a ceremonial council, in St. James' Palace in London.

The Queen’s coffin is likely to be taken to the Palace of Holyroodhouse, the Guardian says, adding that the plan also includes a ceremonial procession to St Giles’s Cathedral on the Royal Mile in Edinburgh.

According to the same report, the coffin will next be flown to London.

The Politico report stated that the casket might be transported to London by royal train.

On D+5 - D-day plus five days - a ceremonial procession through London will transport the coffin from Buckingham Palace to the Palace of Westminster. Westminster Hall will host a service.

According to the Politico article, the Queen will lie in the state in Westminster Hall from D+6 to D+9, and visitors will be allowed to pay their respects.

With the Queen lying in state, the rehearsal for the detailed funeral plans will be held.
