Lightning visit from Prince Harry: King Charles had to change plans. Prince Harry's unannounced visit may not have had an entirely positive impact on King Charles, who is suffering from cancer.

The meeting between Prince Harry and King Charles at Clarence House reportedly only lasted around 30 minutes before an emotional King Charles left in tears for Sandringham. “You don’t want his blood pressure to go up. The king is not doing very well, no matter what type of cancer it is, he is undergoing treatment," said royal expert Robert Jobson.
