Prince George and Princess Charlotte will attend the Queen's state funeral today. The Queen's great-grandchildren will join the King and their parents the Prince and Princess of Wales in the procession at Westminster Abbey today as they mourn the monarch. The nine-year-old future king and his seven-year-old sister will walk through the church, in procession behind the Queen's coffin as it is carried by the military bearer party.
It is the first time that the pair will use their new titles in public - Prince George of Wales, and Princess Charlotte of Wales. It is thought the pair are the youngest royals to take part in a royal funeral procession. They both attended Prince Philip's memorial service in March, and are expected to attend the committal service later in the afternoon at St George's Chapel, Windsor.

Their brother Prince Louis, aged four, who delighted crowds at the jubilee service, is not expected to attend - due to his age.
The Times reports that their parents 'thought hard before deciding that they were ready to take part in a procession' in front of the crowd, that includes world leaders and foreign royalty
The doors of Westminster Abbey opened at 8am, ahead of the arrival of the first mourners for the funeral of the Queen.
The King’s Guards trooped through the gates of Abbey, with two soldiers stationed at the metal gates awaiting the start of proceedings.
At 6.30am this morning, Westminster Hall closed to mourners looking to pay their respects to the Queen as she was lying in state.
Mourner Chrissy Heerey, the last person in the queue, visited the coffin in Westminster Hall twice.
After first queuing at 5:15pm on Sunday and going through the hall at 1:15am, she rejoined the queue at 2:30am.
She said: "[I wanted to go the second time] because it’s so quick and it’s so momentous. I didn’t feel as though I’d done it justice.
"There were a lot of people but everybody was very solemn, everybody was very respectful.
"Everybody gave each other room so they could have that final moment.”
