Prince Harry will embark on a solo trip to New York City in September during the UN General Assembly High-level Week and Climate Week to advance his patronages and philanthropic initiatives, including work with African Parks, The HALO Trust, The Diana Award, Travalyst, and The Archewell Foundation. This trip follows his recent tours with Meghan Markle to Nigeria and Colombia. Coincidentally, Prince William's Earthshot Prize Innovation Summit will also be held in New York on September 24, although it is unclear if William will attend. The brothers, who reportedly haven't spoken in two years, are expected to avoid each other during their overlapping visits. Additionally, Kate Middleton, who is undergoing cancer treatment, shared her diagnosis publicly earlier this year.
