Members of the Royal Family gathered in Edinburgh for the Thistle service, where Queen Camilla and the Duke of Edinburgh were formally appointed to Scotland's

highest order of chivalry, the Order of the Thistle.

The Order of the Thistle honors 16 knights, chosen from individuals who have held public office or made significant contributions to national life, along with additional Royal knights. This prestigious honor is bestowed solely by the monarch, with recent recipients including anthropologist Professor Dame Sue Black, lawyer Baroness Helena Kennedy, and Scotland's first black professor, Sir Geoff Palmer.

The knights participated in a procession from the city's Signet Library to the chapel, adorned in distinctive green velvet robes and white plumed hats. Each knight wore a badge featuring St Andrew with a halo, suspended from the collar.

The Duke of Rothesay and the Duchess of Edinburgh also attended the service at St Giles' Cathedral, which was part of the royal family's Holyrood Week stay in Scotland.
