"The Royal Foundation of The Duke and Duchess of Cambridge and The Duke and Duchess of Sussex has today announced the conclusions of a review into its structure, and how it will best support Their Royal Highnesses with future charitable activity,"
"Later this year The Royal Foundation will become the principal charitable and philanthropic vehicle for The Duke and Duchess of Cambridge. The Duke and Duchess of Sussex will establish their own new charitable foundation with transitional operating support from The Royal Foundation."
A source toldPeoplethat the separation has been a "natural progression."
"A review of The Royal Foundation is something that had previously been announced,” said the source.
"This is part of [the couples’] diverging paths, which hastened a look at the foundation."
According to the publication, the couples separated their joint "court" at Kensington Palace earlier this year by creating two separate offices - Meghan and Harry’s office relocated from Kensington Palace to Buckingham Palace, where the Queen resides, while William and Kate’s office resides in Kensington Palace, where they live with their three children.
Since the change, Meghan and Harry have moved to Windsor Castle’s Frogmore Cottage with their son Archie.
Prince William and Kate Middleton have officially changed the name of the foundation they once shared with Meghan Markle and Prince Harry.

Prince William's status as heir to the throne has left his hands tied.
According to People's source, "the Duke of Cambridge has less flexibility [in his charity work] because of his constitutional obligations."
The sourced also noted that his brother, Prince Harry "is now married, has started a family and is not constitutionally bound. It is a natural progression."
The statement from Kensington Palace also revealed that while the royal foursome will not work together within The Royal Foundation of The Duke and Duchess of Cambridge and The Duke and Duchess of Sussex, they plan to "work together on projects in the future, including on The Foundation’s mental health program, Heads Together."
"The Duke and Duchess of Cambridge and The Duke and Duchess of Sussex are incredibly proud of what they have achieved together through The Royal Foundation. They are especially proud to have established a charity that has had, and will continue to have, significant long-lasting impact, changing lives for the better," the statement continued.
