It’s been a few weeks now since Prince Harry and Meghan Markle gave their shocking tell-all interview to Oprah Winfrey, but the ripple effects from it are still being felt around the globe. Now, a royal expert is speaking out to say that Prince William’s rift with his younger brother Harry is the hardest thing the future king has gone through since losing his mother, Princess Diana.

“There’s no doubt this is one of the hardest things that William has gone through, the hardest since his mother died. He feels he has lost his brother and his best friend,” Duncan Larcombe, a journalist and author of “Prince Harry: The Inside Story,” told OK! Magazine.

This comes after royal expert Katie Nicholl told Entertainment Tonight that William is upset by various claims that Harry made in his interview.

“We’re hearing reports that Prince William felt quite affronted by the claims that Harry made in the interview, not only to the suggestion of racism within the royal family,” Nicholl said. “We’ve also heard through friends of William who have spoken to the newspapers over here that he really rejects that suggestion from his brother that he feels ‘trapped’ by the firm, that he feels trapped by his future role,”

“If you speak to the sources close to William, they say this is very much not the case,” she added. “He’s very willing to embrace his destiny as a future king, and he’s very happy to step up to his responsibilities.”

During his interview with Oprah, Harry claimed, “My father and my brother, they are all trapped. They don’t get to leave. And I have huge compassion for that.”

Two days after the interview, the royal family issued a brief statement in response.

“The whole family is saddened to learn the full extent of how challenging the last few years have been for Harry and Meghan,” the statement read. “The issues raised, particularly that of race, are concerning. While some recollections may vary, they are taken very seriously and will be addressed by the family privately. Harry, Meghan and Archie will always be much loved family members.”

William and Harry are scheduled to reunite on July 1, at a memorial for their mother, Princess Diana, that is being unveiled at Kensington Palace. However, it remains to be seen if the brothers will have made peace by then.

“Clearly we’re quite a ways off from seeing any healing of this rift, but certainly my understanding from the Cambridge camp is that if everything is going to be scrutinized and dissected in the media, then there’s really no chance of them moving on from this,” Nicholl said. “I think that you’re going to hear less and less about the current state of the relationship with the brothers for the simple reason that every time something is leaked to the media, it sets those peace talks back.”
