Operation Menai Bridge, the code name for plans related to the king’s death, is well underway as “death is a possibility” for the 75-year-old ailing royal, who’s battling cancer.

When Queen Elizabeth II ascended the royal throne in 1952, plans for Operation London Bridge started shortly after.

The plan, the codename for operations to take place after her death, included details like the announcement of her death, mourning, her state funeral and King Charles III ascension to the throne.

After the queen died in 2022, the former Prince of Wales, who waited more than 70 years to wear the crown, became the oldest person in British history to accede to the throne.

And he wasn’t able to enjoy his new role for very long.

In January 2024, less than one year after his May 2023 coronation, Charles underwent a “corrective procedure” to treat benign prostate enlargement.

In February, only one month after his procedure, the palace announced that cancer – not prostate – was discovered.

“I would like to express my most heartfelt thanks for the many messages of support and good wishes…As all those who have been affected by cancer will know, such kind thoughts are the greatest comfort and encouragement,”  Charles writes in a statement shared February 10, 2024, on the royal family’s social media accounts.

“William has taken on a bigger role, and Charles has drawn him in on much of the decision-making,” a source says

Recently, the king returned to public-facing duties, but sources reveal that he’s really struggling.

“He’s making public appearances, but they’re for shorter periods of time,” the anonymous person says.” He’s often whisked in by helicopter and then whisked out. After an engagement, he needs a good rest.”

What happens when he dies

After Charles dies, Prince William, the heir apparent to the British throne, will become king and his wife Kate Middleton will be queen consort.

After an official announcement is made to the public, the new king will deliver a broadcast to the nation, like Charles did when his mom died.

The late king will lie in state in the Palace of Westminster for mourning and his last resting place will most likely be in the royal vault in King George VI Memorial Chapel at Windsor Castle.

When the time comes, the royals will be ready for a funeral fit for a King.

“The palace is giving the impression that Charles is on the mend, but he’s still very sick,” an insider tells In Touch in an August 2024 interview. “Officials will make sure a funeral for the king meets his wishes and expectations while following proper protocol.”
