Prince Harry's new book focuses its most controversial moments on his strained relationship with his brother WiIliam, the Prince of Wales, say insiders who have read advance copies of the tome.
The Duke of Sussex's memoir Spare will be out in the shops on January 10 and it is being reported that his brother will bear the brunt of the criticism Harry is expected to direct at the Royal Family. William's wife Kate, the Princess of Wales, is also said to be in the firing line.
The book's publishers have described Spare as "a landmark publication full of insight, revelation, self-examination". They say it is written with "raw, unflinching honesty".
