The Queen's children carried out the traditional Vigil of the Princes around the coffin of their late mother in St Giles' Cathedral, Edinburgh.
The symbolic move sees four people position themselves at each side of the coffin to stand guard for a short time - today's event lasted 10 minutes.
King Charles III took up the role alongside his three siblings, the Princess Royal, the Duke of York and the Earl of Wessex.
About 20,000 people have been waiting in a mile-long queue for several hours to enter St Giles' Cathedral in Edinburgh, where the Queen's coffin lies at rest.
