Prince Harry's tell-all book will carry the title 'Spare'.

The book title is a possible reference to Harry’s role growing up as third in line to the throne, behind his father, Charles, now King Charles III, and older brother, William, now Prince of Wales.

"It's an interesting choice, that he feels that is so significant that it's worthy to be the title," Ford told Gareth Parker on 6PR Breakfast.

"What we still don't know and what I'm really keen to find out is if any edits have been made in recent weeks, we know he wanted to but it's not been confirmed that he was allowed to."
