With the death of his mother Queen Elizabeth on Thursday, Prince Charles has finally become king of the United Kingdom and 14 other realms, ending a wait of more than 70 years - the longest by an heir in British history.
Charles, 73, became monarch immediately after the death of his mother at her Scottish Highland retreat on Thursday, sparking tributes at home and abroad.
He is due to return to London from Balmoral, where the 96-year-old queen died "peacefully" after a year-long period of ill health and decline.
Also on Friday, the new king is expected to hold his first audience with Prime Minister Liz Truss, who was only appointed on Tuesday in one of the queen's last ceremonial acts before her death
