There have been persistent rumors that there was a rift brewing between Prince William and Prince Harry for a while now in the British press. The Royal Family has been dealing with a number of difficulties lately, including Prince Andrew's connection to Jeffrey Epstein and the racist cruelty that Meghan Markle has dealt with from the tabloids, but the apparent chilliness between the formerly tight William and Harry has been a constant.
Speculation began earlier this year when the Royal Foundation, Harry and William's charitable organization, split up. According to the press release:
"These changes are designed to best complement the work and responsibilities of Their Royal Highnesses as they prepare for their future roles, and to better align their charitable activity with their new households."
