The Duke and Duchess of Cambridge have been careful to protect Prince George, seven, Princess Charlotte, five, and Prince Louis, two, from the spotlight, and their attendance would also take three spots from older relatives.
The children are thought to be too young to join the royal procession that will follow the Duke’s coffin on foot within the grounds of Windsor Castle, the Daily Telegraph reported.
Covid-19 restrictions mean only 30 people will be permitted in St George’s Chapel, in the castle grounds, for Saturday’s funeral.
There has been no confirmation of who will attend, but Buckingham Palace has said they will cover all of Philip’s children and grandchildren.
Prince Harry is believed to be in quarantine in the UK after flying in from California yesterday on a BA flight. Others in attendance could include the Duke and Duchess of Gloucester, the Duke and Duchess of Kent, Prince and Princess Michael of Kent, Princess Alexandra, the Earl of Snowdon and his sister Lady Sarah Chatto.
Royals and close friends who do not attend will be able to watch a live stream of the funeral. This will use the same footage as the BBC, ITV and other broadcasters but with no commentary.
