King Charles' health: The alarming warning sign Prince Harry just dropped

Prince Harry's remarks made during the BBC interview about King Charles are set to leave some royal fans concerned about the monarch's health.

The Duke of Sussex talked to the broadcaster on Friday after he lost his legal challenge to Britain changing his security arrangements after he stepped down from royal duties.

During his interview, Harry said more than once that he wants a reconciliation with his father and other family members.

 "Life is precious. I don't know how much longer my father has. You know, he won't speak to me because of this security stuff," he told the broadcaster after implying that his father might have role in denying him the level of security he desires.

His remarks about the expectancy of Charles's life amid the monarch's cancer treatment may lead many observers to wonder whether he knows something  about his father's health that others don't.

Harry might have his issues with the royal family but given his status and sources within the family and the palace, the possibility of him being aware of anything alarming can't be ruled out.

The king was briefly admitted to a hospital  in March due to what was called side effects of his cancer treatment.

According to multiple reports, the palace did not inform the Duke of Sussex about his father's hospital stay and he learned about it through the media.
