Future of the Monarchy Unveiled: Prince William's Ideas for Crown's Next Evolution Will 'No Doubt' Meet Opposition From 1 Major Royal

Prince William's plans for the British monarchy when the Crown falls on his head are likely to have one senior royal calling "off with his head!"

Anne, Princess Royal, is known to favor her mother, the late Queen Elizabeth II's motto of "never complain, never explain," which also extends to a desire to keep the monarchy functioning just as it has for over 1,000 years. The hardworking royal, 73, who is recovering from an accident at her home on June 23, also doesn't like King Charles III's current "slimmed-down monarchy," which the Prince of Wales is set to keep in place when he accedes to the throne.

"Well, I think the 'slimmed-down' [monarchy] was said in a day when there were a few more people around to make that seem like a justifiable comment," the Princess Royal shared during an interview before Charles III's coronation.

Despite Anne's objections, William is set to "create a monarchy that blends the best of the old and new for the 21st century."

The future king is reportedly "coming after" the carriages, costumes, music and theater of the monarchy he will one day lead, a royal insider spilled. This led royal expert Richard Eden — who spoke to a friend of the future king recently — to ominously reveal: "what he told me left me worried about the future of the monarchy."

Eden shared his conversation with the Prince of Wales' pal while examining the "diminished" Buckingham Palace balcony royal appearances at Trooping the Colour since Elizabeth II died.

"When the older members of the family retire, His Royal Highness won't be inviting anyone else to become working royals," Eden added. "It remains to be seen if he will even want his two younger children to be working royals."

The British monarchy is one of only a handful left in the world that still maintains its opulent pomp, pageantry, medieval rituals and centuries-old court etiquette, which Eden suggests could be on its way out. The formerly grand royal courts throughout continental Europe long ago became known as "bicycling monarchies" thanks to efforts by governments to curtail royal grandiosity throughout the 20th century. "They process on bicycles — not in a carriage or Rolls-Royce," a former courtier shared.

Charles III is also seen as a "modernizing monarch," which is in direct contrast to his late mother's "business as usual" approach to monarchy, which retained all the theater. However, his heir was also predicted by many other insiders and analysts to eventually bring the "drastic" changes to the Crown.

"I think William is wonderful," an ex-palace insider shared in 2021. "He has the character to make an excellent British monarch, but he just doesn't understand what this monarchy is all about, and that is pageantry. Britons want the mystery and bowing and the gold carriages and fairy tale visuals although they will never admit to it."
