The Princess of Wales has a strong focus on "discipline" and follows a "regimented daily routine," in order to balance life as a working mother-of-three and the responsibilities of a future Queen, a royal expert says.

Hilary Fordwich highlights that Catherine, who has an important role as the Princess of Wales and mother to a son second in the royal line of succession, is meticulous about planning out her days in order to maximise her time.
