The ghostwriter of Prince Harry's memoir Spare has hinted at "inadvertent mistakes" as he appeared to defend the book.
As readers begin to make their way through the memoir's 407 pages, some have pointed out several inaccuracies within it.
These include claims by Harry he received an X-box for his 13th birthday, years before the games console was released, and that he was at Eton when he learned the Queen Mother died.
It has now been shown that he was in fact skiing in Klosters with his dad King Charles and brother Prince William at the time.
However, ghostwriter J.R Moehringer, who was also the author behind Andre Agassi's best-selling memoir Open, has now taken to Twitter to seemingly defend Spare.
He tweeted a quote by Mary Karr, author of The Art of Memoir, which said: "The line between memory and fact is blurry, between interpretation and fact. There are inadvertent mistakes of those kind out of the wazoo."
Meanwhile, he also shared several passages from Spare, where Harry admits that his words are how he remembers it.
One said: "Whatever the cause, my memory is my memory. It does what it does, gathers and curates as it sees fit, and there's just as much truth in what I remember and how I remember it as there is in so-called objective facts."
He also shared the quote from the book directly after Harry talks about receiving the X-box as a present from his mother Princess Diana, who died just weeks before, where he says "my memory was no longer recording things as it once did".
It comes as historians also pointed out yet another inaccuracy in the book, this time when Harry refers to his great-great-great-great-great-great grandfather', King Henry VI who founded Eton College and died in 1471.
Henry VI's direct lineage ended after his son Edward died childless - meaning Harry's great-great-great-great-great-great grandfather was actually King George III.
Meanwhile, it has been revealed that the English language edition of Harry's controversial memoir sold more than 1.4 million copies on its first day of publication.
Penguin Random House, who published the headline-grabbing autobiography Spare on Tuesday, has reported its largest-ever first-day sales total for any non-fiction book published by the company.
According to the publisher, 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 January 10 when it first hit bookshop shelves.
Speaking about the record sales, president and publisher of the Random House Group Gina Centrello said: "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."
