Now that Prince Harry and Meghan Markle are back home in California after a whirlwind Colombia tour, the couple is reportedly re-examining a future visit to the United Kingdom. Amid reports that Harry is homesick for his life across the pond, a royal expert says Meghan has one “major condition” for returning to the U.K. with her kids – and it goes beyond security concerns.

In addition to ensuring that the Sussex family regains taxpayer-funded security–a privilege they lost once they stepped down as working royals–Meghan has also reportedly made it clear she doesn’t plan to stay with her in-laws when she’s visiting. Royal author and expert Tom Quinn told The Mirror, “Meghan has said she’s only prepared to return to England if she and Harry have a place of their own and the security they both feel is essential. Meghan will never return to the UK and stay with her husband‘s relatives.”

The couple previously lived at Frogmore Cottage from 2019 to 2020 and still had ownership of the property until they were evicted from the royal residence last year. Harry reportedly viewed the decision as a “slap in the face,” Quinn told The Mirror at the time.

“Harry was absolutely furious and in tears about being evicted from Frogmore,” the royal author previously said. “He felt his father had no right to do it and that it was purely vindictive. Harry couldn’t see that choosing to stop being a working royal would inevitably mean being deprived of his royal residence. Harry took it as a cruel rejection.”

In addition to searching for a new “permanent home,” Prince Harry has been embroiled in a four-year court battle to reinstate U.K. police security for his family, citing concerns about the safety of his wife and kids. While his request was initially denied, he won the right to appeal the court’s decision in June.

If these conditions are met, Quinn told the publication that there’s a possibility that the couple’s two kids could visit the U.K., and potentially–after some mediation–develop a relationship with their British cousins.

“If the couple manage to find a permanent home and sort out the security issue they will certainly want to bring their children to the U.K. but it’s going to take a lot of diplomacy to get to the point where Archie and Lili are able to develop a genuine and warm relationship with their cousins George, Charlotte, and Louis,” Quinn added.
