The Duke and Duchess of Cambridge's three children are not expected to be among the 30 mourners who attend the Duke of Edinburgh's funeral, The Daily Telegraph understands. The Cambridges have been careful to protect Prince George, seven, Princess Charlotte, five, and Prince Louis, two, from the public gaze, and made clear from the outset that they would shield them from the pressures of royal life while they were young. While the ceremony on Saturday will be very much a family occasion, the children are understood to be considered too young to join the procession that will follow the Duke's coffin on foot within the grounds of Windsor Castle. Their attendance would also take three coveted spots for older relatives who have known the Duke for most of their lives. A Buckingham Palace spokesman has confirmed that the Duke's children and grandchildren would all attend alongside Her Majesty. With spouses, if all attend, they would number 20 in total. The remaining ten are thought likely to comprise the Queen's cousins, including Princess Alexandra, 84, who remains a working royal, although she has not undertaken an official engagement since last July.
