Buckingham Palace has reportedly decided not to make public the result of the investigation into Meghan Markle's alleged staff bullying. As it didn't reveal the reason behind the decision, a royal expert believes it may stem from the fears that the Sussexes will hold a new interview with Oprah Winfrey that may ignite another spat with the royal family.

Royal commentator Duncan Larcombe believes the royal family fears that Prince Harry and Meghan Markle may "unleash a world of pain" if they once again have a talk with Oprah Winfrey. In fact, he thinks it's one of the factors behind the Firm's decision not to release the finding of the Duchess of Sussex's bullying inquiry that may result in "a war of words."

For starters, the royal couple slammed the royal family when it first had an interview with the Queen of All Media. "I think the reason they are not publishing any of this is because the Palace is running scared of the Duke and Duchess of Sussex," Larcombe said, via Express.

He continued that the Palace might be aware that if it published the report, the Sussexes might play the victim again and hold an interview that would cause "another world of pain." This assumption might have stemmed from the photo that saw Prince Harry and Meghan Markle pulling into Oprah Winfrey's mansion in Montecito, California, last month.

This sparked the fears that another bombshell interview was in the works. The Duke of Sussex was spotted driving in the front seat, while a woman, believed to be the actress Janina Gavankar, was sitting next to him, and his wife was in the middle seat behind them.

Sources told MailOnline, per The Mirror, that the three stayed at Oprah Winfrey's home for about an hour before they left.

The investigation in question is about the claims that the former "Suits" star bullied some of her staff members. However, the public might never have the chance to know what transpired, as reports in June suggested the investigation result would never be published.

The Palace reportedly just improved its HR policies and procedures after seeing the probe's result. Queen Elizabeth II allegedly privately funded the investigation, but it had been repeatedly said that the Firm had no plans to make any public statement about it or even reveal the changes publicly.

An independent law firm was said to carry out the inquiry and some of its participants were left disappointed over the report "being buried." The Sunday Times explained it was left to secrecy to protect everyone who took part in it and avoid further misunderstanding with Prince Harry and Meghan Markle.
