Copies going Spare! Prince Harry's new paperback version of his autobiography sits in 73rd place in book charts after selling just 3,000 in its second week

Prince Harry's new paperback version of Spare is languishing in 73rd place in the UK charts after selling scarcely 3,000 copies in its second week of publication.

The Duke of Sussex chose not to give any interviews to publicise the paperback edition of his bombshell autobiography which came out on October 24.

Its publisher Penguin Random House confirmed it was not updated from its hardback form, viewed as a somewhat unusual move for an international bestseller.

The hardback edition came out in January 2023 - breaking records at bookshops as it became Britain's best-selling book last year, with more than 700,000 copies sold.

But Harry's decision to give no publicity or updates for the paperback is likely to have hit potential sales and given it a lowly place outside the Official UK Top 50.

The 3,000 sold compares with the 12,000 copies shifted of Richard Osman 's latest novel or almost 10,000 sold of Jeremy Clarkson 's Diddly Squat: Home To Roost.

The re-issue of Spare contains a reprint of claims made by Harry against his estranged family including allegations that Prince William broke his necklace and shoved him onto a dog bowl which smashed during a particularly explosive row.

The Duke also recalled private family conversations between himself, his father King Charles III and brother.

It claimed William teased Harry about his panic attacks, that Charles put his own interests above his second son and saw Harry reference taking cocaine, marijuana and psychedelic mushrooms and his enjoyment of the TV show Friends.

Harry also shone a spotlight on difficulties between his wife Meghan Markle and Kate – including the Princess's reaction to the Duchess of Sussex saying she had 'baby brain'.

And he used the book to make claims that William called Meghan 'difficult', 'rude' and 'abrasive', and that Charles refused to allow Meghan to join Harry in Scotland as the late Queen was dying.

Penguin Random House announced on August 26 that Spare's paperback version would be published in 16 languages worldwide, with the same cover image and a newly-designed package but 'the contents of the book are unchanged'.

Questions were raised over whether Harry would update his memoirs with a new chapter, considering that has happened within the Royal Family over the last year.

This has seen his relationships with his family continue to break down, the King diagnosed with cancer - which saw Harry fly to London to see his father for barely 30 minutes - and his children, Archie and Lilibet, have become Prince and Princess.

Harry's choice not to add to the revelations has been viewed by some as an olive branch and an attempt to try to improve the relationship with his family.

Spare became an instant publishing sensation when it was first published on January 10 last year, selling more than six million copies in both print and audio worldwide.

The title, ghostwritten by journalist J.R. Moehringer, also set a new Guinness World Record for the fastest selling nonfiction book of all time.

The English language edition sold more than 1,430,000 units in all formats and editions in the US, Canada and the UK on its first day of publication.

It April, fellow author Osman claimed Harry had already made £22million ($27million) from Spare despite it only being out in hardback at the time.

Harry was understood to have clinched a £16million ($20million) advance as part of a £32million ($40million) four-book deal in June 2021 following a bidding war.
