Grant Harrold, who worked closely with King Charles III, has pushed back against the perception that the monarch was distant with his sons.
He described Charles as “very funny” and “very sweet” with William and Harry, determined to fill the void left by Princess Diana’s death.
According to Mr Harrold, the king took his boys fishing and shooting in Scotland, offering a very different kind of parenting from Diana’s theme-park trips.
He said both parents brought “something very different to the table,” shaping the princes’ characters in unique ways.
Mr Harrold stressed that Charles made time for his sons despite royal duties, showing a more personal side rarely seen by the public.
