The Duke of Sussex’s autobiography is the fastest-selling non-fiction book ever, recording figures of 400,000 copies so far across hardback, ebook and audio formats on its first day of publication.
Larry Finlay, managing director of Transworld Penguin Random House, said; “We always knew this book would fly but it is exceeding even our most bullish expectations.
“As far as we know, the only books to have sold more in their first day are those starring the other Harry (Potter).”
