A new royal portrait has been revealed!

The British royals unveiled a new portrait of King Charles III, the Queen Consort and the Prince and Princess of Wales on Saturday.

The new portrait, which shows the four royals side by side in all-black mourning attire, was taken the night before Queen Elizabeth II’s funeral on September 18 at Buckingham Palace. The photo was taken on the night they were hosting world leaders in London for the funeral at a reception at Buckingham Palace.

Charles, 73, was officially proclaimed reigning monarch of the United Kingdom on September 10. At the televised ceremony, the Accession Council made the official proclamation of King Charles in the State Apartments of St James’s Palace in London.

Watched by Prince William – in his first official role as the Prince of Wales – and Queen Camilla, the proclamation was read in the Palace Picture Gallery before the Privy Council (composed of senior Cabinet Ministers, magistrates and Church of England leaders): “The Crown of the The United Kingdom of Great Britain and Northern Ireland has only and rightly fallen to Prince Charles Philip Arthur George,” read the Council Secretary.

“We… hereby publish and proclaim with one voice and assent of tongue and heart, that by the death of our late sovereign, Prince Charles Philip Arthur George is now in happy memory our only rightful and rightful liege, Charles III.”

A poignant portrait of the new monarch was released last month, showing the king hard at work at Buckingham Palace with the famous red box containing documents that require his attention on 9/11, just three days after Queen Elizabeth’s death.

In a scene so often associated with Queen Elizabeth, King Charles sat at a desk handling the daily dispatch of papers from leaders across Britain, the Commonwealth and the world.

The story goes on

Behind Charles hung a black and white photograph of his late parents, Queen Elizabeth and Prince Philip. It was given by the couple to their father, King George VI, for Christmas in 1951 – the last holiday season before he died in February 1952.

In addition, William and Kate, both 40, were married by King Charles III just a day after the Queen’s death on September 8th. made Prince and Princess of Wales. Staying true to their new titles, the couple headed to Wales as soon as possible – just a day after the royal mourning period ended.

It was a particularly poignant visit. Those who know the couple have compared their time there in the early years of their marriage to the time the late Queen Elizabeth and Prince Philip spent in Malta.

Those close to William and Kate also say Wales holds a special place in the couple’s hearts – rooted in their first home, where they lived when Prince George was born, and reflected in their decision to marry George and Taking Princess Charlotte to Cardiff over the weekend to celebrate the late Queen’s Platinum Jubilee.

When their visits took place, plans for a large-scale investiture such as that of William’s father, Charles, in July 1969 were far from their thoughts. The royal couple are more interested in further deepening their ties with the Welsh people and representing and celebrating the modern nation of Wales. They also plan to return to Wales before the end of the year.

The Prince and Princess of Wales last paid an official visit to the country in June as part of Queen Elizabeth’s Platinum Jubilee Weekend, celebrating her historic 70th jubilee to the throne. They were visiting Cardiff and were accompanied by two special guests: their eldest children, Prince George and Princess Charlotte.

The day was particularly poignant for George, who is set to become the next Prince of Wales after his father. The visit mirrored Prince William’s first official trip to Wales when he was around the same age. In March 1991, Prince William joined his parents, Princess Diana and Charles, in Cardiff. The excited crowd presented the young prince with daffodils – the national flower of Wales – as he made a tour of Llandaff Cathedral.
