Prince Harry has flown back to the United Kingdom to see his father, according to media reports, after the shock announcement on Monday from Buckingham Palace that King Charles III has cancer. Harry, who arrived in London Tuesday from California, has been involved in a long-running, public falling out with his family in the years since he and wife Meghan, Duchess of Sussex, stepped back from royal duties, though the duke did make a brief visit to the UK for Charles’ coronation last year.
