In a stunning development that has reportedly left Buckingham Palace reeling, Princess Anne has disclosed the existence of a previously unknown decree from the late Queen Elizabeth II, potentially altering Princess Catherine’s position and influence within the Royal Family.

Sources close to the royals claim the revelation occurred during a private family gathering shortly after Christmas at Sandringham. “This wasn’t expected… not by anyone,” one insider said. The decree, described as a handwritten note or informal instruction from the Queen before her passing in 2022, allegedly outlines specific guidance for Catherine’s future responsibilities — emphasising her role in modernising the monarchy and granting her enhanced advisory privileges.

The news has stunned King Charles and Queen Camilla, with the atmosphere shifting instantly upon Anne’s disclosure. Palace aides describe the King as “momentarily speechless,” processing the implications for succession planning and Catherine’s growing prominence.

Princess Anne, known for her straightforward manner, reportedly felt it was time to honour the Queen’s wishes amid Catherine’s triumphant return to duties following her cancer remission. The decree is said to reinforce Catherine’s status as a key figure in the “slimmed-down” monarchy, possibly including expanded patronages or informal veto powers on certain initiatives.

While details remain guarded, the timing — emerging just after the festive season — has intensified speculation about 2026 transitions. Insiders suggest it redefines Catherine’s behind-the-scenes influence, positioning her as a bridge between tradition and contemporary royal life.

Buckingham Palace has declined comment, stating family matters are private. However, the revelation underscores the late Queen’s enduring legacy in shaping the institution’s future. As the Waleses prepare for a pivotal year, this secret decree could mark a subtle but significant shift in royal dynamics.
