Prince Harry and Meghan Markle reportedly have a lot of time before deciding to attend King Charles III's Coronation.
Expert, Dr George Gross, who is King’s College London's visiting research fellow in Theology, said that if the official invitations sent out by the firm have not had a RSVP deadline mention then the Duke and Duchess of Sussex can still take their time to decide if they want to attend.
He told Express.co.uk, "In a bygone era, if we’re going back to the Tudors and the Stewards, if you received a summons to the Coronation, attendance wasn’t optional, you couldn’t say ‘I’m not free’, you’d attend. But obviously in the 20th and 21st century, things have been different."
He added, "Given that they’ve got the royal box, in a sense, there’s flexibility on this one."
The royal box is a designated area where Royal Family members sit during the service, a tradition that has taken place in past coronations, and so there will be space available for the couple.
"The other reason that there’s always a little bit of flexibility is people never know for sure if they will attend with things like health and so on," he explained.
"They’re always last minute [cancellations], it’s the same as planning any great event or even, if we take it back to the ordinary person, if you try planning a party and somebody changes their mind last minute, there’s always some flexibility, and there are always cancellations, and they’re always last minute attendees."
He surmised, "So, there’s always a little bit of room. Because of the royal box, I think you’ve got more flexibility."
