The British royal family gathered in Edinburgh for a ceremonial celebration of one of Scotland's most prestigious traditions. King Charles III, accompanied by Queen Camilla and their sons Prince William and Prince Edward, attended the Order of the Thistle installation at St Giles' Cathedral, where they formally recognised new members of this ancient chivalric order. The formal proceedings, complete with traditional regalia including ornate velvet robes and plumed headpieces, formed part of the royal household's annual week-long residence in Scotland.

The Order of the Thistle represents Scotland's highest honour, conferring recognition on 16 knights and acknowledging Scottish citizens who have made significant contributions to public life and national affairs. The cathedral service included ceremonial elements such as a guard of honour and the formal installation of new members, concluding with a reception and luncheon at the royal residence. The event marked the continuation of Royal Week festivities, during which the monarch traditionally maintains a presence in the Scottish capital.
