The meticulous planning surrounding the eventual passing of King Charles is encapsulated in "Operation Menai Bridge," a moniker inspired by a notable suspension bridge in Wales. This operation, revealing the extent of the forethought given to royal contingencies, was subtly hinted at in an episode of "The Crown" which depicted a close call Charles had with an avalanche. During this episode, the Queen's secretary, discussing the prince's safety, remarks, "We have contingency plans in place for all members of the royal family, Menai Bridge is no exception. It's the code name for the Death of the Prince of Wales."

Such preparations have been a longstanding part of royal protocol. The period of planning and mourning that follows a monarch's death, as witnessed during the days post Queen Elizabeth II's passing, offers a glimpse into what might be expected when the time comes for Operation Menai Bridge to be enacted.


Simon Morgan, a former Royal Protection Officer, indicated that planning for Charles' eventual funeral began almost immediately after his ascension. "Unfortunately, as of tomorrow morning planning for Operation Menai Bridge will start in earnest," Morgan explained, acknowledging the inevitability of such events given the King's age and the responsibilities that come with his position.
The specifics of Operation Menai Bridge remain confidential, but it's anticipated to mirror Operation London Bridge, the codename for Queen Elizabeth II's passing. This means that upon Charles' death, a sequence of notifications will commence, starting with his family, then the Prime Minister, followed by Commonwealth nations and heads of state, and finally, the general public.
A poignant aspect of royal protocol was highlighted when Queen Elizabeth II died; King Charles insisted that all family members be informed before any public announcement, showcasing his concern as both a monarch and a father.
The death of King Charles will prompt immediate changes, including the pinning of an official notice at Buckingham Palace's gates and the lowering of flags to half-mast. Prince William will assume the role of King instantaneously, although his coronation may not occur until several months later.
