Prince William reportedly “stepped in” and helped his younger brother Prince Harry during a dispute with their grandmother, the Queen.
A royal expert claims it was William who backed Harry and Meghan Markle’s wish to break from Kensington Palace so the Sussexes could establish their own court.
It emerged earlier this month that Meghan and Harry will soon have their own team separate from William and Kate’s.
Their official household will be based at Buckingham Palace where they will have a separate communications team from the Cambridges.
And royal commentator Omid Scobie has claimed Prince William was instrumental in securing the funding for Meghan and Harry to go out on their own.
Speaking on podcast On Heir, he said: “Charles and the Queen did not want the Sussexes to have their own individual household, and indeed how could they because the money has to come from somehwere.
“Prince Harry is not a direct heir to the throne, and only a direct heir to the throne can have their own household.
“They won’t be having their own exclusive team just for themselves and from what I understand their budget for the team wasn’t particularly big.”
He added that William understands how vital Meghan and Harry are to the royal family’s image and so was eager to help.
“It was actually Prince William who had to step in and fight to get Harry a little bit more money to spend on building a team because he understands what this means to Harry and how much he wants to achieve and also how important Harry and Meghan are for the image, the brand and the future of the royal family,” he said.
“As much as William is being set up for this statesmen-like role and William and Kate are the nation’s favourites, but on the global stage it is very much about the Sussexes, in their commonwealth roles, they’re very much global ambassadors for the royal family.”
Omid also revealed the couple’s new communications officer has worked in the UK and the US.
He said: “They’ve hired Sarah Latham who is a former PR director from the British PR company Freuds which is a big PR powerhouse but also has a massive background in politics.
“She’s America, dual heritage, very much in line with what the couple are all about and I think it helps having someone who understands both cultures.
“We have seen that over time the difference between US and UK work culture can cause some friction in the workplace.
“But a lot of their team will be shared amongst the Duke of York, Prince Edward, Princess Anne the same communication staff that are working across the general office there will also be at their disposal too.”
Kensington Palace said at the time of the split: “The Queen has agreed to the creation of a new Household for The Duke and Duchess of Sussex, following their marriage in May last year.
“The Household, which will be created with the support of The Queen and The Prince of Wales, will be established in the spring.
“This long-planned move will ensure that permanent support arrangements for The Duke and Duchess’s work are in place as they start their family and move to their official residence at Frogmore Cottage .”
The Sussexes are expecting their first child in the coming weeks and are due to move into the renovated Frogmore Cottage imminently.
A spokeswoman for Kensington Palace said they did not wish to comment.
