Prince Harry and Meghan, Duchess of Sussex, have also been invited to the service, but they did not say if their children, Prince Archie Harrison and Princess Lilibet Diana, were also on the guest list.
Dr George Gross, visiting research fellow in theology at King’s College London and co-founder of the British Coronations Project with Dr David J Crankshaw, told Express.co.uk the royal offspring could attend. He said arrangements have been made in the past for those who would not be able to sit through the hours-long ceremony in its entirety.
He explained how at the Coronation of King George V on June 22, 1911, Winston Churchill, who was then Home Secretary, received an invitation for himself and his wife Clementine.
The ceremony took place less than a month after Clementine had given birth to their son, Randolph, on May 28. As a result, the King made special arrangements to accommodate her.
Dr Gross said similar arrangements for the Sussex and Waleses’ children to leave part-way through King Charles’s Coronation could be made.
But he added there would be an added complication due to the service being televised.
He said: “There’s a way they could have [the children] there for some of it. It’s possible we could see the Wales and Sussex children. But it’s a long service so who knows.
“It is also harder with TV the way it is today. But given that Charles and the Queen [Elizabeth II] both witnessed a coronation, it seems quite likely Prince George will be there.”
Dr Gross added: “A lot of young children at home of his age will be interested to watch. It’s a spectacle with a lot to see.”
The eldest of William and Kate’s children, Prince George, nine, and Princess Charlotte, seven, are expected to attend the Coronation. They often step out for important events and went to the funeral of Queen Elizabeth II alongside their parents.
But it is not clear if Prince Louis, who turns five next month, will be there on May 6.
Harry and Meghan’s children are younger still. Archie will turn four on the date of the Coronation and Lilibet will be just shy of two.
Charles attended his mother’s Coronation in 1953 when he was four, but Princess Anne didn’t attend because she was deemed to be too young at the age of two.
The ceremony itself could last for hours although Charles is understood to want parts streamlined.
Full details have yet to be made public, but Dr Gross suggested the Homage part of the ceremony, in which every member of the British nobility pays their respects to the monarch, could be dropped or shortened.
The crowning of Camilla, Queen Consort, would also add an extra layer to the ceremony which did not happen at Elizabeth II’s Coronation in 1953.
The Anointing, which may be televised for the first time ever at Charles’s Coronation, the Crowning and the delivery of the Coronation Oath would also be included as key parts of the ceremony.
Dr Gross explained the oath is an integral part of the ceremony with the Acclamation and Recognition also viewed as very important.
He said: “This happens before the Oath, with the congregation asked, Do you recognise this person as your King or Queen?
“This part of the cereony dates back to the Anglo Saxon period when monarchs were elected by the elite. Monarchs can’t be anointed without that being done.
“In many ways, those in Westminster Abbey [on May 6] represent us. It’s a really important moment where the public are asked if they recognise this monarch.”
Dr Gross predicted Charles’s Coronation would also be relatively long in duration because of a lot of music has been announced.
On the possibility of the Anointing being televised for the first time, Dr Gross said it was possible, adding: “Will it make a difference to remove that mystery and magic? Our hunch is it will not.
“If it is to be televised, we won’t know until a couple of days before. We can make this argument because lots of people will watch the Coronation on TV. Telling people now won’t generate extra interest.
“But an announcement a couple of days before might generate a bit more. But we don’t know. There’s a higher chance, but we don’t know for sure.”
