As the Queen's beloved grandchildren stand beside their grandmother's coffin in Westminster Hall, many royal fans may have noticed Kate Middleton and Meghan Markle are not among the young generation of royals not present, nor Prince George or Princess Charlotte.
It is understood that most of the spouses of the Queen's grandchildren - including the Princess of Wales and the Duchess of Sussex - are not in attendance to allow the cousins to come together on their own to mourn.
Mike Tindall, Edoardo Mapelli Mozzi and Jack Brooksbank are also among the royal spouses not taking part tonight, and they will remain at their respective homes in Windsor. The 15-minute vigil lets mourners continue to file past the Queen lying-in-state, while the royal grandchildren honour their 'Grannie' in person.
