Prince Harry's much-anticipated "raw" memoir gets a title and a release date

After more than a year of anticipation, Prince Harry has finally announced a title and release date for his memoir.

The book, which will be released on January 10, will be called Spare.

The 416-page memoir will find Harry telling his story with "raw, unflinching honesty," covering topics including his childhood, military service and his marriage to Meghan Markle.

The title is a reference to the old saying about the nature of the royal system and that it is best to have two sons; "an heir and a spare."

Harry has often accused his family of emotionally neglecting him and the title seems likely to prompt speculation the book will detail his perceived treatment at their hands.

The book's delay led to rumours that Duke of Sussex was hesitating to say too much about his family, or was perhaps revising the narrative after his grandmother, Queen Elizabeth II, died in September. 

Harry will be donating a portion of the proceeds from the book to Sentebale, the HIV/AIDS-focused charity in southern Africa he helped to found in 2003.

He will also donate to WellChild, a charity that supports children with disabilities and their families.
