Queen Elizabeth II's granddaughter Princess Beatrice has been assigned a bigger role and responsibility after the death of her grandmother.

After the queen's death at the age of 96, changes have taken place in the royal household, including titles and roles in the palace. King Charles has ascended the throne, while Camilla is now Queen Consort. Prince William and Catherine, Duchess of Cornwall and Cambridge, have been granted the titles of Prince and Princess of Wales. Meanwhile, Princess Beatrice, the eldest daughter of Prince Andrew and Sarah, Duchess of York, is now a counsellor of state.

Prior to the queen's death, the four counsellors of state were her sons – Prince Charles and Prince Andrew – and Charles' two sons – Prince William and Prince Harry. The position of counsellor of state was vacated after Charles became Britain's king.

Now that she has assumed the role of counsellor of state, Princess Beatrice is expected to attend council meetings, sign documents and receive the credentials of new ambassadors. The royal title was given to Princess Beatrice as she was the highest candidate in the line of succession who was above 21 years old, Cosmopolitan UK reported.

Counsellors of state were known to fill in for Queen Elizabeth II when she was unable to carry out her duties whenever she got sick or was abroad. Princess Beatrice and the other counsellors of state will fulfil this duty for King Charles III when the latter become unable to attend important gatherings. Aside from the counsellors of state, Camilla could also step in for her husband should there be a need for it.

Queen Elizabeth II, who assumed the monarchy in 1952 and reigned for over 70 years, was the longest-reigning monarch in British history.

The state funeral for Queen Elizabeth II will take place at Westminster Abbey on Sept. 19, the royal family said.

On Sunday, the queen's coffin arrived in Edinburgh Castle and elaborate proclamation ceremonies were held for King Charles III in Scotland, Wales and Northern Ireland.

The queen's daughter, Princess Anne, was seen curtsying in front of her mother's coffin as it entered the Palace of Holyroodhouse in Edinburgh Castle on Sunday.
