King Charles was first photographed at work from the famous red box.
The new monarch, whose late mother Queen Elizabeth received one of the iconic containers every day of her reign, including weekends, was photographed on official state duties in an eighteenth-century room at Buckingham Palace.
Christmas was the only time his late mother did not receive a similar red box.
They contain documents from UK government ministers as well as documents from Commonwealth authorities.
The picture of Charles at work, taken by the Press Association’s Victoria Jones, was published on Friday night (24/09/22) but was taken on September 11, days after the Queen’s death on September 8 aged 96 at her beloved Balmoral estate.
When the Queen reached her record 70 years on the throne earlier this year, Buckingham Palace released a similar picture of her sitting with a red box, taken in the drawing room of Sandringham House, where she traditionally spent her anniversary, since it was there that her father died.
Charles is seen in the image sitting at a gilded desk, reaching for papers, including one tied with ribbon, while a framed black-and-white photograph of his parents sits in the background.
British leather firm Barrow Hepburn and Gale previously confirmed that boxes for Charles were in production, with a company spokesman saying the king would initially receive more than six boxes, all of which would feature the new royal cipher.
Each box has its own combination lock and is believed to be red, as that shade was the favorite of Prince Albert, Queen Victoria’s consort.
Others believe the cause dates back to the late 16th century, when Francis Throckmorton, the representative of Queen Elizabeth I, presented the Spanish ambassador Bernardino de Mendoza with a red briefcase filled with black puddings.
The king is now believed to be staying at his home in Birchhall, Scotland, to begin his new job and mourn his “lovely mum” in private after 10 days of national mourning in the UK and public appearances by members of the royal family, including official visits to Scotland. , Wales and Northern Ireland by Charles.
Ahead of the Queen’s state funeral on September 19, he said he hoped “flights of angels” would “sing you to rest”.
