King Charles III reportedly decided to evict Prince Harry and Meghan Markle from Frogmore Cottage after allegedly crossing the line with the Duke of Sussex's revelations against Camilla, Queen Consort, in his book, "Spare." Though the monarch seemingly gets the support of the U.K. people, a royal expert claimed it was against the will of his late mother, Queen Elizabeth II.

Dr. Tessa Dunlop believed King Charles made a big mistake by evicting Prince Harry and Meghan from their Frogmore home and offering it to his disgraced brother, Prince Andrew. The Sussexes' rep confirmed that His Majesty requested the couple to vacate their last royal property after making several allegations against the royal family in their Netflix docuseries, "Harry & Meghan," and "Spare."

The historian revealed many people in Britain were "gleeful" with the move. Still, she believed it was against the wishes of Her Majesty, weakening the pair's remaining ties with the royal family. She continued that the queen wanted to keep her grandson on board, adding that the "optics were terrible."

Dunlop told Mirror that she knew the controversial prince just "lobbed several verbal hand grenades" at the royal family and the institution where he formerly belonged. However, she couldn't blame him due to his weak position and the pain of being sidelined.

She added that the monarchy could effortlessly weather the storm if it were confident. And with the coronation looming, King Charles has a lot of other things to do.

Hence, with the eviction of Prince Harry and Meghan from Queen Elizabeth's generous gift of Frogmore Cottage, King Charles just goes directly against the conciliatory style of his mom. He even melded the issue about the Sussexes with that of Prince Andrew by asking him to leave his much-bigger home, the Royal Lodge, to move to the five-bedroom house.

Dunlop stressed that this move could even affect the monarchy's image weeks before the coronation, which she described might see Prince Andrew's attendance but not his son and American daughter-in-law.

Meanwhile, King Charles reportedly decided to let Prince Harry and Meghan leave their U.K. home after learning the duke's claims against his wife, Camilla. He believed his child had "crossed the line" with his revelations, painting the queen badly.

Sources said the king was outraged by the accusations, like when Prince Harry accused Camilla of leaking royal stories to the press and referring to her as "the villain" in TV interviews while promoting his memoir. King Charles allegedly started to act when the aides revealed the details from the book and eventually began the eviction process a day after the memoir hit the shelves.
