The core of the feud shifted permanently after the publication of Harry’s memoir, Spare. The book crossed lines that William considers unforgivable: quoting private conversations from royal residences, detailing arguments inside Nottingham Cottage, and sharing personal text messages between Catherine and Meghan.
The disclosures did not just embarrass the family; they undermined William's concept of brotherly solidarity. As reported by outlets like Newsweek, royal loyalists and public observers pushed back sharply against Harry's digs, including his remarks suggesting other royal men married out of institutional suitability rather than genuine love, a comment widely seen as an insult directed straight at William's marriage.
Public sentiment across the United Kingdom reflects these battle lines. YouGov polling trends spanning 2024 through early 2026 regularly indicate William’s net favorability sitting steadily in positive double digits, often exceeding +50%, while Prince Harry's approval metrics remain pinned in negative territory among domestic British demographics. This polling buffer gives William the freedom to stand firm. He faces very little domestic pressure to compromise; British voters by and large support his decision to prioritize royal duties over reconciling with a brother who attacked the family business.
