PRINCE HARRY’S MEMOIR has become the fastest-selling non-fiction book in the UK since records began in 1998.

According to Nielsen BookData, which collects and provides information on distribution and sales measurement of books, Harry’s headline-grabbing autobiography Spare sold 467,183 copies in its first week.

The memoir, which hit the shelves on January 10, includes claims that his brother William physically attacked him and teased him about his panic attacks, and that the new king put his own interests above Harry’s. 

The data released by Nielsen shows that the book has broken the previous record of 210,506 set by the first Pinch Of Nom cookbook – written by Kay Allinson – in 2019.

The Nielsen BookData does not include e-books or audiobooks and refers only to the sale of physical copies. 

Spare, which was ghostwritten by JR Moehringer, is the only non-fiction book to make it into the top 10 fastest-selling books in the UK since records began.

Since January 1998 JK Rowling has dominated the chart, with four of her Harry Potter novels sitting at the top, while Dan Brown’s The Lost Symbol claims the fifth spot ahead of Spare at number six.

To claim number one on the chart, which looks at the first week of sales only, Rowling’s Harry Potter And The Deathly Hallows sold 2.63 million copies in its first week in 2007.

Despite the memoir hitting shelves in Spain ahead of the official publication date, and a number of extracts leaking in the lead-up to the book’s UK release, Nielsen’s data suggest sales were not negatively affected.

As the duke continued a run of high-profile promotional interviews, he said he “would like nothing more” than for his children to have relationships with the royal family.

His remarks about his son and daughter came despite the criticism he has levelled at his brother William, father Charles and stepmother Camilla.

He also described his late mother, Diana, Princess of Wales, as his “guardian angel” and said she is with him “all the time”.
