Prince Harry's memoir Spare is set to be released next week, on January 10, with the contents of the book already causing controversy for the Royal Family. 

This is due to the news that the book reveals that Prince William and Prince Harry had a physical argument, and the Duke of Sussex sharing more personal details as well.

But ahead of the book's highly anticipated release, Prince Harry is taking part in a tell-all interview to tease the book. 

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. 

Previously, the Prince and his wife, Meghan Markle, released a Netflix documentary, Harry and Meghan, which told their story as a couple. 

This followed their courtship, marriage and eventual departure from the Royal Family, sharing the pressure they felt and the media's input into their decision. 

The interview is the first time the Prince has spoken out in this way since the couple's groundbreaking interview with Oprah in 2021.

When is the Prince Harry Interview on?

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

The show will last until 10.40pm with presenter and journalist Tom Brady conducting the interview that took place in the Prince's California home. 

In a preview released by ITV, Prince Harry said: "how staying silent is ever going to make things better" before he discussed his thoughts on the monarchy.

Later in the clip, Bradby is seen asking Harry about his brother's potential reaction to the interview and clip, to which Harry replied: "He'd probably say all sorts of different things."

Harry: The Interview is on ITV at 9pm on Sunday, January 8.
