The biography, which reached bookshelves in 2025, represents the culmination of four years of extensive research and numerous freedom of information requests.
It achieved the coveted position of Sunday Times number one bestseller following its release.
Mr Lownie has established himself as a respected authority on royal affairs, having previously penned acclaimed works examining the lives of the former King Edward VIII, who gave up the throne in 1938, and Lord Mountbatten, who was the uncle of the late Prince Philip.
The royal commentator's latest work has attracted considerable attention from readers seeking insight into the Queen's second son.

Critics have responded with striking assessments of Mr Lownie's work, with one reviewer characterising it as a "damning cannonball of truth."
Another commentator has credited the biography as serving as a "catalyst for Andrew's de-princing."
Readers on Amazon have offered similarly emphatic verdicts, with customer reviews labelling the book "phenomenal" and "grimly fascinating" in their appraisals of its contents.
