The Countess of Wessex was visibly moved as she watched her children stand vigil over the Queen's coffin at Westminster Hall on Saturday night.
Lady Louise Windsor, 18, and James, Viscount Severn, 14, who are the late monarch's youngest grandchildren, joined their cousins as they stood guard.
Their parents, Prince Edward and Sophie, watched the vigil from a viewing platform, and the Countess looked full of emotion and pride.

The Queen's eight grandchildren stood vigil over her coffin
The Wessex children had joined their mother in the viewing gallery on Friday as their father stood vigil over the Queen’s coffin with his siblings, King Charles, the Princess Royal and the Duke of York.
The Earl and Countess have largely kept their children out of the public eye over the years, aside from big formal events such as Trooping the Colour. Lady Louise and James also took part in the Queen’s Platinum Jubilee celebrations in June.
Earlier on Saturday, Edward and Sophie surprised the crowds during an impromptu walkabout outside Buckingham Palace following a formal reception.
