Sources have said that the April 3 cut-off date has now passed and staff have still not been told whether the King’s estranged son and his wife are accepting his invitation to attend, even though the event is now just a month away.
The issue is said to be causing a ‘headache’ for organisers, who are trying to finalise details such as seating arrangements, cars, and security for VIPs attending the historic ceremony on May 6.
And even if they did decide to attend, the Duke and Duchess of Sussex would not be allowed to stand on the Buckingham Palace balcony next to the King and Queen because they are no longer working royals.
The monarch will be joined by a select few who show the ‘heartbeat and future of his family’ and who have dedicated their lives to public service. Charles and Camilla will arrive at Buckingham Palace from Westminster Abbey in a Gold State coach, followed by the ‘final group of 15’ which would not make room for the Duke and Duchess of Sussex.
