A source told the publication, “They are planning a formal division of their joint royal household, which is based at Kensington Palace, and the creation of separate courts to reflect their increasingly different responsibilities.
“The brothers have leant on each other and looked after each other since their mother died. But now they have their own families, they no longer rely on each other as before.”
Another source said: “William and Harry double act has naturally been supplanted by the two couples and their families.”
The source also said the changing duties of the brothers are playing an important role in the decision of William and Harry to split up.
They said: “When William becomes the Prince of Wales, he will take on a lot of extra responsibility.
“Harry and Meghan have non of that, and seems ambitious about forging their own paths.
“If you have one private office tying to manage both, things get difficult.”
