• Prince Harry is "getting regular updates" about the investigation into Diana's "Panorama" interview, a report says
  • The duke was criticized by tabloids for not joining Prince William in publicly commenting on the probe
  • A source close to Harry says the press is trying to "drive a wedge" between the brothers

The claims that Prince Harry doesn't support his older brother Prince William and the probe into Princess Diana's explosive 1995 interview with journalist Martin Bashir are "offensive," a source close to the Duke of Sussex told Sky News.

The Duke of Cambridge released a statement earlier this week saying that he is backing the BBC's investigation into the circumstances that led to Princess Diana's controversial "Panorama" interview. However, Prince Harry was criticized by tabloids for not joining Prince William in publicly commenting on the matter and was accused of failing to protect his late mother's legacy.

A source "close to" Prince Harry, however, said that these claims were "utterly horrid and offensive." The insider added that just because the Duke of Sussex hasn't released a statement doesn't mean he is not supportive of the inquiry.

"You do not need a public statement to imagine how he is feeling privately, people know how much his mother means to him," the source told Sky News. "He has spoken out bravely in the past about loss and grief, and the immense impact it has had on him."

The insider added that the press appears to be trying to create a rift between Prince Harry and Prince William over this matter.

"Sadly, some people are not just seeing this as a drive for truth, but also trying to use this as an opportunity to try to drive a wedge between the brothers," the source said.

"Harry is getting regular updates and is aware of everything that is happening," the insider added.

Meanwhile, Princess Diana's brother, Charles Spencer, said he wasn't satisfied with the BBC's investigation, which is being led by former Supreme Court judge Lord John Dyson.

"As I’ve told the BBC this evening, I’m not at all satisfied with the parameters they’ve set around their enquiry into the @BBCPanorama interview with Diana of 25 years ago tonight. Lord Dyson must be free to examine every aspect of this matter, from 1995 to today, as he sees fit," Earl Spencer wrote on Twitter.

The inquiry will look into allegations that Bashir forged bank documents to coerce Princess Diana into participating in the tell-all "Panorama" interview where she famously said, "There were three of us in this marriage."

Meanwhile, royal fans have mixed opinions about the matter. Some accused the royal family of trying to rewrite history, while others claimed that Spencer was cashing in on his sister. A number of royal watchers believe the probe is unnecessary as Princess Diana willingly participated in it, while some think everyone should just move on.

"Someone's broke and running out of money? Exploiting a dead sister to cash in? Diana has said in her own words what has occurred," one commented. "She was sane, lucid, adult, and obviously recorded the facts as she meant for us to hear them. Let her rest in peace."
