A royal expert is speaking out this week to claim that Kate Middleton “may step in” to take the place of Prince Harry at the unveiling of a statue of the late Princess Diana at Kensington Palace if he can’t go due to the birth of his daughter.

Daily Mail reported that while Harry is due to head back to the United Kingdom this month for the unveiling of the statue on July 1, which would have been Diana’s 60th birthday, he and his wife Meghan Markle are expecting a baby girl next Thursday. In fact, Meghan’s due date is on what would have been Prince Philip’s 100th birthday.

However, royal expert Russell Myers said that the birth of the baby girl could derail Harry’s plans to attend the event. Myers also said that the shocking claims that Harry has made about racism from within the royal family could make his reunion with his brother Prince William “very uncomfortable.”

“Will there be an appetite for him to keep on criticizing his family in that way? He’s potentially going to be standing shoulder-to-shoulder with his brother when they unveil the Princess Diana statue,” he said. “That could make it very, very uncomfortable, [although] whether he comes over is a matter for debate at the moment because they are expecting their second child.”

“Meghan is about to give birth, one would presume – they said early summer – so whether he will, whether he won’t,” Myers added. “Maybe Kate will step in to not have William do it on his own.”

In his new mental health docuseries “The Me You Can’t See,” Harry appeared to take a swipe at the royal family when he talked about the “shame” felt by his relatives when confronted with mental health problems.

“As parents, as siblings, certainly from what I’ve learned, there’s an element of shame we feel because we’re like, ‘How could we not have seen it?'” Harry said. “But we all know when people are suffering and people are struggling that we’re all incredibly good at covering it up.”

Harry also attacked his father Prince Charles’ parenting style in the docuseries.

“My father used to say to both William and I, ‘Well, it was like that for me so it’s going to be like that for you,'” Harry claimed. “That doesn’t make sense. Just because you suffered doesn’t mean that your kids have to suffer. In fact, quite the opposite.”
