According to royal author Robert Hardman's book on King Charles III, Prince Harry left friends within the royal circle "astonished" with his insinuation that Prince William married Kate out of duty rather than love. This assertion was allegedly made during an episode of the Netflix docuseries Harry & Meghan released in December 2022.
In the series, Prince Harry defended his choice to marry Meghan Markle, stating, "For so many people in the [royal] family, especially obviously the men, there can be a temptation or an urge to marry someone who would fit the mold as opposed to somebody who you perhaps are destined to be with...The difference between making decisions with your head, or your heart."
The royal biographer highlighted that opinions within the royal circle were divided over Harry's remarks about his sister-in-law and her marriage to the future King of England. The source close to the royals expressed that, "On top of all the other breaches of trust, here was Harry making a blatant attack on Catherine. For William, this was the lowest of the low."
This development adds another layer of strain to the already complicated relationship between the two brothers.
