“There’s a lot of worry that Harry could tell all in a book deal or even follow Meghan’s lead and make a podcast,” the source continued. “He’s hinted he has discovered secrets during the hearings — particularly regarding the treatment of him and Meghan — that would shock us all. It is a veiled threat essentially that he will tell all if it doesn’t go the way he wants it to.”

Though there are concerns that the Prince may be gearing up to speak out once more, it’s understood that he’s feeling “overwhelmed” by the continuous stream of legal battles, which have now stretched over three years since his departure from royal life.

Speaking to The Telegraph after a two-day hearing at the court of appeal, Harry admitted that the removal of his security detail had been “difficult to swallow.” He noted that among all the legal disputes he has faced since stepping down from royal duties, the fight over his personal protection “always mattered the most.”

However, much of the appeal proceedings this week—along with last year’s initial hearing—were conducted in private, involving what has been described as “highly confidential” information submitted to the court.

Following his appearance, Harry said that people “would be shocked by what’s being held back.” He added, “My worst fears have been confirmed by the whole legal disclosure in this case and that’s really sad.”
