Prince Harry sits down with ITV tonight ahead of the release of his explosive memoir 'Spare'.

The Prince's tell-all autobiography has been making headlines after various news outlets obtained excerpts of the book just days before it officially hit shelves on January 10.

The Sun, The Daily Telegraph, Page Six and more translated copies of Harry's book after some copies accidentally went on sale early in Spain.

The leaked snippets have reportedly featured some jaw-dropping claims made by the Duke of Sussex from being physically attacked by his brother Prince William to the now King being jealous of him and his wife, Meghan Markle. 

What time is Harry: The Interview on tonight on ITV?

Harry: The Interview is set to see him share details of the Duke and Duchess's strained relationship with King Charles and Prince William as well as why they decided to leave. 

In the UK, Harry: The Interview will be shown on ITV on Sunday, January 8 at 9pm.
