Prince Harry's autobiography has broken records after selling more than 1.4 million copies on its first day of publication.
Penguin Random House, who published the headline-grabbing autobiography Spare on Tuesday, say the figure is their largest ever first-day sales total for any nonfiction book.
The publisher says the English language edition of Spare sold more than 1,430,000 units in all formats and editions in the United States, Canada and the UK on its release date of January 10.
Speaking about the record sales, president and publisher of the Random House Group Gina Centrello said: “While many books by public figures can be fairly categorized as ‘celebrity memoir,’ Spare is not that.
“Vulnerable and heartfelt, brave and intimate, Spare is the story of someone we may have thought we already knew, but now we can truly come to understand Prince Harry through his own words.
“Looking at these extraordinary first day sales, readers clearly agree, Spare is a book that demands to be read, and it is a book we are proud to publish.”
Penguin Random House says the book has even gone back to press for additional copies to meet demand in the United States.
It comes despite the contents of the book being leaked a week early, with copies even appearing in bookshops in Spain one week before official release.
In the bombshell memoir the Duke of Sussex takes aim at King Charles, Queen Consort Camilla, Prince William and Kate Middleton, as well as sharing details of how he coped with the death of Princess Diana.
Harry also goes into detail about his and Meghan Markle's time in the Royal Family.
One of the most talked-about claims in Spare is that a physical confrontation took place between him and older brother William at Nottingham Cottage in Kensington Palace in 2019.
The book says William had called Meghan “difficult”, “rude” and “abrasive” – comments which the younger brother said parroted “the press narrative” about his wife.
