Copies of the intimate memoir were mistakenly released in Spain five days before the official publication, prompting much of its contents to make headlines across the world.
Harry also gave several interviews ahead of the book launch, doubling down on claims that some royals leaked damaging stories to the tabloid press about him and his wife Meghan in order to protect their own reputations.
The royal family has not commented on the book or any of the interviews given by Prince Harry.
