The two brothers appear to be at logger heads, with their relationship seemingly taking a turn for the worst in recent times. In the ITV documentary ‘Harry & Meghan: An African Journey’, the Duke of Sussex hinted that all was not well between William and himself. He told Tom Bradby: “Inevitably stuff happens. But we’re brothers, we’ll always be brothers.
“We’re certainly on different paths at the moment.”
Royal commentator, Kate Nicholls, believes that the Duchess of Cambridge has a big role to play in helping to heal the brotherly rift and is uniquely equipped to do so.
She told Closer magazine: “Kate's been in the royal family a lot longer than Meghan and she has a natural tendency for teamwork.
“Behind the scenes, she's known to play the role of peacemaker. She's aware it is not in anyone's best interest to feud.
“If there's a chance to make a secret pact with Meghan to team up more, she will want to do that.”
Part of the reason for the deterioration in brotherly relations can be traced back to advice William tried to give Harry in 2016.
At the time Harry was courting Meghan and the Duke of Cambridge warned his brother about rushing the affair.
According to sources, Harry resented this brotherly intervention into his private life.
The royal princes are also missing the the crucial support they received from the Queen’s longstanding private secretary Christopher Geidt.
Mr Geidt retired from his post in 2017, but played a key role in smoothing over any grievances between the boys and the rest of the family.
He also helped mediate their relationship with their father, Prince Charles, with whom the princes are said to have a complex relationship.
Ms Nicholls also believes that Meghan and Kate must join forces to save the Royal Family as the Queen heads towards retirement.

As the New Year approaches, the 93-year-old Queen remains very much in control.
However, there is already speculation that she may opt to hand over day-to-day control to Charles in 18 months, when she turns 95.
The royal expert believes the possibility of the Queen stepping aside was likely to “force” the Duchess of Sussex, Meghan, 38, and the Duchess of Cambridge Kate, 37, to work more closely together.
She said: “I think after a festive break, both Kate and Meghan will know that joint ventures to support the Queen are not only part of their duty, but also good for the public image.
“Kate knows the pressure is on her and Meghan to save the royal family, to an extent.”
Prince Andrew’s ongoing troubles, which have seen him stripped of his royal duties, are likely to present an opportunity for other members of the Royal Family to increase their profiles.
Ms Nicholl said as a result, his charities may be divided up, resulting in Kate and William, and Meghan and Harry, putting on a “united front”.
She added: “The Queen turns 94 this year and there’s a plan in place to relieve her of her pressures, which is why she’s calling on the four to step up.
“Although the Cambridges and Sussexes have their own charities, I think the Queen’s move towards retirement will force them to work closely with each other.”
