Barnaby to unload in 'warts and all' book

Former deputy prime minister Barnaby Joyce is due to have a tell-all autobiography released in August.

He's had a run in with Johnny Depp, found out he was a Kiwi and had a baby boy with a former staffer - now Barnaby Joyce is penning a book.

The former deputy prime minister's autobiography is scheduled to be released in August after being picked up by New Holland Publishers.

The publishers say it will be a "warts and all" account of his personal story and his commitment to people in the bush.
