Kate and Wills’s star aide joins Harry and Meghan’s rival camp

ANY divorce is painful, but the split between Prince William and Prince Harry’s households is proving particularly complicated.

It was announced last month that Harry and Meghan would be quitting the Royal Foundation they share with William and Kate.

And I can reveal the Duke and Duchess of Sussex will be taking one of the Royal Foundation’s most distinguished directors with them to run their new power base. She is Natalie Campbell, pictured with Kate, an award-winning ‘social entrepreneur’ who is the Royal Foundation’s ‘director of insight and innovation’.

‘Natalie will be a real loss to William and Catherine,’ a courtier tells me. ‘She has done brilliantly for the Royal Foundation and formed a bond with Meghan when she worked with her on the cookbook for survivors of the Grenfell fire. Her loss will be keenly felt by the Cambridges.’ Harry and Meghan lost no time in establishing their own charitable organisation.

I can disclose that its name, The Foundation of the Duke and Duchess of Sussex, was trademarked the very next day after the announcement of the split. Their spokesman confirmed Natalie’s appointment and added: ‘A full board and trustees will be appointed in due course.’

A sign of the tensions ahead came this week when Harry and Meghan used their new Instagram account to publicise 15 environmental causes to their 8.8 million followers, with no mention of William’s charity, United For Wildlife.

‘It was unbelievable,’ one of Wills and Kate’s friends tells me. ‘Harry knows how passionate William is about the charity, it was a real snub.’

Kensington Palace sources insist William was not left ‘disappointed’ by the omission. Such magnanimity will be needed in months to come.
