An official portrait of King Charles has been issued, showing him performing his new duties as head of state for the first time.

Just days after the Queen's passing on September 8, the King is shown on September 11 during his first days of work as king.

The red box is the daily delivery of documents from ministers in the United Kingdom and other realms, including Canada and Australia.

Additionally, letters from officials of the Commonwealth and other nations may be found here.

The red box in the picture, which was photographed in Buckingham Palace, contains official documents that must be signed.

At Sandringham House, she was captured on camera in the saloon.

The palace published a photo of the Queen sitting with her red box in February, when she reached the milestone of 70 years on the throne.

An Italian oil painting by Francesco Zuccarelli from the 18th century adds to the mood.
