Prince Williamwill probably have to save his Big Apple sightseeing for another trip across the pond.
The Prince of Wales, 41, isreturning to New York Citynext month for two days, including a special event for a cause close to his heart: the second Earthshot Prize Innovation Summit in New York City on Sept. 19. The event serves as a rev up to the 2023 Earthshot Prize awards ceremony, whichwill take place in Singaporeon Nov. 7.
However, Prince William likely won’t linger in New York, most probably heading back to the U.K. shortly after his engagements in the United States wrap. That’s becauseKing CharlesandQueen Camillaare also heading overseas that week. Buckingham Palace announced on Thursday that the royal couple will head to France from Sept. 20 to Sept. 22 for a state visit. King Charles, 74, and Queen Camilla, 76, were originally scheduled to visit the country in March, but theypostponed the tripdue to riots happening across France at the time.

While Prince William is not required to be in the U.K. when his father is traveling, he is one of the King’sCounsellors of State— one of the royals who can carry out constitutional duties for King Charles if he is abroad or unwell.
However, Prince Harry and Prince Andrew are no longer working members of the royal family — Harry, 38, stepped back as a senior working royal and relocated to California in 2020, while Andrew, 63, wasstrippedof his military titles and patronages in January 2022 due to his association with convicted sex offender Jeffrey Epstein. Therefore, Parliament felt it was best to expand the cohort to include two additional people who could be called upon to stand in for King Charles.
King Charles' two other siblings —Princess AnneandPrince Edward— were tapped for the royal role, and they wereofficially made Counsellors of Statein December 2022. The role is a return for Princess Anne and Prince Edward as they were both previously Counsellors of State toQueen Elizabethbefore they moved down in theline of successionto the throne.

Prince Harry will also be in Europe next month. The Duke of Sussex will attend the annual awards event forWellChild, a charity for seriously ill kids of which he is a patron, in London on Sept. 7.

Prince William was supposed to attend the Earthshot Prize Innovation Summit in New York City last September butcanceled the trip statesideafter the death of his grandmother Queen Elizabeth. Still, he addressed the Summit via video.
“Although it is the saddest of circumstances that means I cannot join you in person today, I am pleased to join you in video form as you gather in New York for the Earthshot Prize Innovation Summit,” the Prince of Wales said. “During this time of grief, I take great comfort in your continued enthusiasm, optimism and commitment to the Earthshot Prize and what we are trying to achieve.”
“Protecting the environment was a cause close to my grandmother’s heart, and I know she would have been delighted to hear about this event and the support you’re all giving our Earthshot finalists, the next generation of environmental pioneers,” he added.
