“She can say what she likes and be warmed. I think it’s wonderful she can do that. The children will be delighted also.” A source told The Daily Beast regarding the Princess of Wales: “Kate has been exceptionally open and honest about her health.

“Making two appearances before the summer break, at Wimbledon and Trooping the Colour, was a clear signal that she is doing well. That is what we are hearing privately as well—it’s not over but there is lots of optimism, lots of positivity.”

“It is obviously still an incredibly worrying time but all the signs are that her cancer treatment, which is ongoing, is progressing well.” Last month, the Princess of Wales made her second public appearance since announcing her cancer diagnosis, attending the Wimbledon men’s final.

Catherine, who is the patron of the All England Lawn Tennis and Croquet Club, presented the men’s singles trophy to Carlos Alcaraz, who beat Novak Djokovic in straight sets. The princess attended the final with her daughter, Princess Charlotte, and her sister, Pippa Matthews.

Before handing Alcaraz the trophy, Catherine spoke to ballboys and ballgirls who lined up around her, and shook Djokovic’s hand.
