Jennie issued a warning against reading too much into things, remarking: “But the very fact that they want to keep the application viable does suggest that, looking to the future, there may be new plans afoot,” and then adding cautiously, “And that of course is positive. I certainly wouldn’t want to put any kind of spin on the interest in moving into America. We shouldn’t try to set up imaginary rivalries between William and Catherine and Harry and Meghan. They’ve got enough problems without us adding more unfounded speculation.”

“But William and Catherine are clearly very popular in the United States. I’ve no doubt that if the Foundation can help with the many issues surrounding mental health worldwide, then that support would be welcomed… and would carry with it a good deal of heft because of William and Catherine.”

Kate disclosed recently that she had finished her chemotherapy for cancer, and just last Thursday 26 September, she stepped out publicly for the first time since the revelation. The Duchess attended the matinee show of the English National Ballet’s Giselle at Sadlers Wells theatre.

Stirred by the performance, Kate shared a heartfelt message via X: “Congratulations and thank you to @ENBallet and @Sadlers_Wells for the wonderfully powerful, moving and inspiring performance of Akram Khan’s Giselle. Creativity at its best! C”.

Kate is also gearing up for her return to Royal duties, announcing this week that she will host her annual charity carol concert at Westminster Abbey in December. The ‘Together At Christmas ‘ event, now in its fourth year, will be aired on ITV on Christmas Eve. She also held her first meeting at Windsor Castle on Wednesday 18 September, an Early Years meeting that supports early child development, a cause close to Kate’s heart.
