King Charles III made a huge sacrifice for his estranged son Prince Harry and his wife Meghan Markle.The 75-year-old monarch hasn't been on speaking terms with the Duke and Duchess of Sussex since their bombshell interview Oprah Winfrey in 2020,

King Charles and Prince William have been accused of "corruption" and "hypocrisy" by campaigners following reports that they profited to the tune of millions from schools, hospitals, other public services and charities.

Prince Harry is embroiled in a long-running legal case in the U.K. to reinstate his police protection. According to a royal expert, his father King Charles worries that the proceedings will affect his ability to rekindle his tumultuous relationship with the Duke of Sussex.

DailyMail contributor and royal author Robert Hardman told Fox News Digital that King Charles, who reportedly hasn't answered Prince Harry's messages, would never leave his door closed.

"Here you have the infelicitous situation where the King’s son is suing the King’s ministers in the King’s courts."

Prince Harry and King Charles have been on the outs for years, but there may be more than just family drama keeping the royal family divided.

Will Prince Harry cause more trouble for King Charles? According to a new report, the monarch, 75, is fearful of how the Duke of Sussex's long-running legal case against the U.K. government to obtain security again may negatively affect the father-son duo’s already rocky relationship.
