Nicky Hager’s new book, Dirty Work, has officially been released and it's made some controversial allegations.

The book centres on the Taxpayers Union and founder Jordan Williams, and includes claims the lobby group has worked with the tobacco industry, and focuses on race-based campaigns. 

Jordan Williams has labelled this 'desperate'. 

"This is three different versions of an allegation that came from nowhere, that every former chair and current chair of the Taxpayers' Union is saying does not exist."
