King Charles III is worried about his son Prince Harry’s finances, according to a new book. The monarch, 75, is reportedly concerned about what might happen once Harry, 39, spends the millions of dollars he earned from a slate of business deals that he and wife Meghan Markle did with companies like Netflix and Spotify.The claim is just one of many salacious tidbits in royal reporter Robert Jobson’s upcoming biography about Kate Middleton, titled, “Catherine: The Princess of Wales.”“The ‘Harry problem’, as it’s known among Palace staff, continues to plague the King,” Jobson alleges in an excerpt of his book published on Daily Mail.
