Working members of the Royal Family will wear military uniform when present at five ceremonial events during this period of mourning Queen Elizabeth II.
These are the Service of Thanksgiving at St Giles’ Cathedral, Edinburgh, the procession to Westminster Hall and service of prayer and reflection, the Vigil at Westminster Hall, the state funeral at Westminster Abbey and the Committal Service at St George’s Chapel Windsor.
It comes after King Charles III accepted addresses of condolence from the House of Lords and the House of Commons at the ancient venue.
He then made a speech, as the King leads the country's mourning of Queen Elizabeth II.
The King quoted Shakespeare in a tribute to his mother, as he addressed Parliament for the first time since becoming monarch.
He said: “As Shakespeare said of the earlier Queen Elizabeth, she was a pattern to all princes living.”
Later on Monday, the Crown of Scotland will be placed on her coffin while it lies in rest in Edinburgh.
Historically, the Crown has been used in ceremonies to represent the sovereign’s presence and it will be placed on Elizabeth II’s coffin by Alexander Douglas-Hamilton, the 16th Duke of Hamilton.
Historic Environment Scotland confirmed it will remain with her while she lies in rest at St Giles’ Cathedral in Edinburgh – where thousands of Scots are expected to go to pay their final respects.
Large crowds are expected to be present at the cathedral, where mourners will be allowed to file past her coffin from about 5.30pm on Monday until 3pm on Tuesday.
After that, the Crown of Scotland will be returned to Edinburgh Castle – where it is usually on display – and will be present for visitors to see when the castle reopens on Wednesday.
