Prince Charles was honored on Tuesday during an event on the occasion of the 50th anniversary of his investiture as Prince of Wales.
He was accompanied by the queen and his wife Camilla.
All eyes were on the Duke and Duchess of Cambridge and the Duke and Duchess of Sussex, because they have not been seen together since December.
But three important members of the royal family were missing from the event.
Prince Philip, 97, was not present, although this can be explained by his recent departure from royal occupation and ill-health.
But Charles’ younger brothers – the Duke of York and the Earl of Wessex – were also absent from the event and no explanation was given for the remarkable absences.
Prince Charles’ sister Anne, the Princess Royal, attended the event.
The royal family was accompanied by the archbishop of Canterbury who paid tribute to the prince at the party, organized by the Queen at Buckingham Palace, and he was also accompanied by friends and representatives of his Welsh charities.
While the Queen and Prince Philip attended the investiture of Prince Charles fifty years ago, two other guests were present to support the King on Tuesday.
Lady Susan Hussey, a lady-in-waiting for the queen, and Sir Nicholas Soames, the conservative member of parliament and an old friend of Charles.
Also at the reception were members of the band The Stereophonics, which in their early days were supported by a subsidy from the Prince’s Trust.
Kelly Jones, the singer and the lead guitarist, said, “We have applied for a few grants from the Prince’s Trust, we needed some money for some speakers, and Prince Charles came to Pontypridd and we met him, we had some money from them. It was great to meet him and to have a few speakers.
“It was the first time we could afford to buy a pair of speakers My dad was a singer, so I stole a lot of his equipment, I think they gave us one grant for £ 500 and one for £ 800. That time it was a lot of money for us.
“Unfortunately, the speakers were stolen a few months later by a bunch of builders, so we had to buy new ones, but yes, it was a very useful start.”
In this latest episode of The Windsors we investigate to what extent Prince William became the beneficiary of the fascination for ruthless media and sometimes of burglary.
Charity representatives at the event were Falkland veteran Simon Weston, 57 years old, who suffered from burns and has since become known for his charitable work.
He is the chairman of charity DEBRA, who supports people affected by Epidermolysis Bullosa.
Patrick Holden, a campaigner for organic food, was also present.
The British Prime Minister Theresa May was at the ceremony, as was the Prime Minister of Wales, Mark Drakeford.
