Prince William is furious that his brother Prince Harry is landing a huge sum of money in just weeks, sources claim.

The Duke of Sussex is set to inherit £7million from a trust set up by his great-great grandmother the Queen Mother, when he turns 40 on September 15.

Harry is set to receive a larger share of the inheritance than his brother, given William is already benefitting from the Duchy of Cornwall wealth.

But the Prince of Wales is reportedly unhappy at the sum, given Harry has stepped back as a senior royal and has subsequently criticised Royal Family members both on TV and in his explosive memoir Spare.

A source told Closer: “William’s pretty disgusted that once again Harry’s going to be cashing out and taking millions back to his Montecito home without lifting a finger for it.

“There’s nothing he can do about it, aside from shaking his head, but if it were up to him, Harry would not be getting this payday.

“William doesn’t think his brother is in any position to be getting this handout and he’s letting it be known that he things it’s a pretty rotten situation.

“William and Kate don’t trust Harry or Meghan one bit, so the idea that Harry’s now cashing in on his great-Granny’s inheritance leaves a very bitter taste in their mouths.”

Since leaving the UK for the US in 2020, Harry has criticised his family and the royal set-up on a number of occasions.

In Spare, he alleged he was left with stitches after a physical altercation with William. He admitted to Oprah Winfrey he was on “different paths” with his sibling and hoped things would “heal”.

Meghan Markle, meanwhile, claimed sister-in-law Princess Kate left her in tears with a comment before her wedding day and made an allegation of racism against an unnamed Royal Family member.

According to Closer, William believes the inheritance shows Harry “is essentially being rewarded after the terrible treatment he’s shown them all” and that it “is just wrong on so many levels”.

Express.co.uk has contacted Kensington Palace for comment.

It comes after a commentator suggested Harry would have missed out on the inheritance had the Queen Mother been aware of what was to come.

Speaking to Fox News, Christopher Andersen said: “Of course, the prince’s great-granny couldn’t have anticipated all the trouble Harry caused the rest of the family. I think she would have cut him out of [the trust] entirely had she known.”
