As thousands continue to queue to see Queen Elizabeth II lying in state at Westminster Hall, some will witness King Charles III, Princess Anne, Prince Andrew and Prince Edward as they hold a 15-minute vigil around the coffin.
An exception was made for the Duke of York, who wore his uniform as a "special mark of respect" for his late mother.
He could be seen cutting a forlorn figure, standing guard around her coffin.
The King led his siblings into Westminster Hall, followed by the Princess Royal and Earl of Wessex, with the Duke of York just behind.

The King, Princess Royal, Duke of York and Earl of Wessex had solemn looks on their faces as they stood vigil near four flickering candles.
King Charles III and his siblings’ heads were bowed throughout as members of the public filed past them, stopping to pay their respects to the Queen.
Members of the Royal Family including James, Viscount Severn, Lady Louise Windsor, the Countess of Wessex, Jack Brooksbank, Zara Tindall and the Duke of Kent were in attendance as the siblings paid their respects to the former monarch.
Queen Elizabeth II’s grandchildren will hold a vigil at her coffin on Saturday – with the Duke of Sussex also wearing his military uniform.
This came after a personal request from King Charles, after it initially appeared that Prince Harry would wear civilian dress.
Prince William will stand at the head, with Harry at the foot.
William will be flanked by his cousins Zara Tindall and Peter Philips, Princess Anne's children.
While Harry will be with Prince Andrew's daughters, Princesses Beatrice and Eugenie.
It comes as more details were revealed ahead of Queen Elizabeth II's funeral, which will see 2,000 people gather at Westminster Abbey on Monday.
Recipients of the Victoria Cross and the George Cross and representatives of the Westminster Parliament, devolved parliaments and assemblies, the Church, and Her Majesty’s patronages are among those who will also attend.
The service will be conducted by the Dean of Windsor, with Prime Minister Liz Truss and Commonwealth secretary general Baroness Scotland reading the lessons, and the Archbishop of Canterbury delivering the sermon.
Some 800 people, including members of the Queen’s Household and Windsor estate staff, will attend the committal service afterwards at 4pm in St George’s Chapel, Windsor Castle.
The Palace confirmed the Queen will be interred with the Duke of Edinburgh in the King George VI Memorial Chapel at St George’s Chapel in a private service at 7.30pm.
