The King has granted a new royal title, following the passing of the late Aga Khan.
Prince Karim Al-Hussaini died at the age of 88 last week and his son, Prince Rahim Al-Hussaini, 53, was named as the Aga Khan V.
And now Buckingham Palace has confirmed that the King has given the new Aga Khan "His Highness".
Charles is continuing a long-standing royal tradition of bestowing the title on the spiritual leader of the world’s millions of Ismaili Muslims.
The late Aga Khan was given the title of "His Highness" by Queen Elizabeth II in July 1957, two weeks after his grandfather unexpectedly made him heir to the family’s 1,300-year dynasty as leader of the Ismaili Muslim sect.
The King was left deeply saddened over the death of the late Aga Khan.

The Queen's filly Estimate, which claimed victory in Royal Ascot's 2013 Gold Cup – the first time in the race's 207-year history that it had been won by a reigning monarch, was an 80th birthday present from the late Aga Khan.

The Aga Khan is considered by his followers to be a direct descendant of the Prophet Muhammad and is treated as a head of state.
A funeral was held in Lisbon on Saturday, before a private burial ceremony in Aswan, Egypt, on Sunday.
