Princess Beatrice is set to receive an important role in the royal family with her uncle King Charles III on the throne.

Beatrice — who is also an Italian "Contessa" and "Nobile Donna" after marrying Edoardo Mapelli Mozzi in 2020 — will likely become a Counsellor of State under the new monarch, The Telegraph reports.

The roles, created under the 1937 Regency Act, are given to the monarch's spouse and the next four adults in the line of succession over the age of 21. The position allows the counsellors to carry out business on behalf of the monarch.

Though Beatrice is currently ninth in the line of succession, she is the fourth adult over 21 — with Prince William, Prince Harry and her father, Prince Andrew, ahead of her. Queen Camilla will also serve as a Counsellor of State.

Though they are rarely called upon, Counsellors of State are able to attend Privy Council meetings, sign routine documents and receive the credentials of new ambassadors to the U.K.

There are a number of "core constitutional functions" that cannot be delegated to Counsellors of State, however — including Commonwealth matters, the dissolving of Parliament (unless expressly instructed to do so by the King), the creation of peers and appointing a new Prime Minister.

Under Queen Elizabeth, the Counsellors of State were Prince Philip until his death last year, as well as Charles, William, Harry and Andrew.

Events of recent years reportedly created pressure for both Harry and Andrew to be removed from their positions and replaced with other working royals, though the Queen did not make any such changes.

On Friday, Beatrice's husband Edoardo Mapelli Mozzi shared a personal tribute to the late monarch on Instagram and shared how "very lucky" he felt that his children were able to spend time with the Queen this summer. The couple welcomed daughter Sienna Elizabeth last year, and he is also a father to a son from a previous relationship.

"Incredibly hard to process the last 24 hours," he wrote. "What an incredible woman and extraordinary mark she's left on the entire world. She was the rock on which modern Britain was built."

"Feeling very lucky that our little ones got to spend wonderful time with her this summer," he said, hinting that the family visited the Queen at Balmoral Castle in Scotland.

Edo concluded the post, which featured a number of photos of Queen Elizabeth through the years, "Rest is Peace Your Majesty. We will miss you so much. Brokenhearted."
