Prince Harry's explosive tell-all autobiography is available for free on Amazon in a shock Black Friday deal - two months before it is set to hit UK bookstores in January.

Amazon's deal is available when customers take out a trial of their audiobook service Audible, and the book is now on the list of free works which can be purchased by Audible listeners during the trial.

The audiobook will not be available to listen to until its release on January 10, but savvy shoppers can sign up for the trial now, select the book and then cancel their account - leaving the audiobook free upon its release.

Royal fans will hear the book read by the prince himself, adding an extra layer to the experience.
