It is the first appearance since the death of Queen Elizabeth II by Prince William and Prince Harry and their wives Kate and Meghan.
The two couples exchanged views with mourners and onlookers who had gathered along the main avenue at Windsor Castle on Saturday afternoon, looking at flowers and personal messages that had been laid outside the property.
It is also the first public appearance for Kate and William (both 40) since wearing their new titles - Prince and Princesse of Wales.
The new King Charles III.
had given them this on Friday in his first speech to the nation.
The relationship between the two couples, who were called "Fab Four" in the British press before Meghan (41) and Harry (37) left the royal family, is now considered difficult.
However, William and Kate are said to have invited Harry and Meghan to the joint appearance, according to a spokesman for the couple.
In a statement released on Saturday along with his wife Kate, Prince William expressed his sadness at the death of the Queen.
It is comforting that all of his three children will still retain conscious memories of their great-grandmother.
George (9), Charlotte (7) and Louis (4) would have spent many vacations with her.
Message from William and Kate
The heir to the throne and Prince of Wales said: 'She was by my side in my happiest moments.
And she was by my side through the saddest days of my life.
I knew that day would come, but I think it will be some time before I really fully appreciate what life without a granny means.”
The fact that she is mourned so much now only shows how much she was loved during her lifetime.
William promised, "I will honor her memory by supporting my father the king in any way I can."
Prime Minister also united
Another high-profile gathering occurred earlier on Saturday at the live televised proclamation of King Charles III.
Former Prime Minister Theresa May and her colleagues Gordon Brown, Tony Blair, David Cameron and Boris Johnson arrived together at St James's Palace in London.
The photo is quite remarkable - after all, the former prime ministers of Great Britain are often politically at odds.
