Copies of Prince Harry's autobiography, Spare, have gone on sale in Spain - five days before its official global release date.

Sky News has seen a copy of the book which includes claims of an altercation with Prince William that caused "scrapes and bruises” on his back. He also admits to taking cocaine.

On the Sky News Daily, Niall Paterson is joined by Sky's Royal correspondent Rhiannon Mills to examine, after the Oprah Winfrey interview and Netflix documentary, what extra insight the book’s 557 pages might offer.
