4BC Drive: Prime Minister Julia Gillard says she is the target of a smear campaign that boils down to nothing and has challenged her opponents to present any evidence of wrongdoing over events that took place 20 years ago.
For the second time in three months, Ms Gillard has publicly addressed questions about her conduct as a Slater Gordon solicitor in the 1990s when she did some legal work on an Australian Workers Union (AWU) account.
"This whole campaign of smear actually boils down to absolutely nothing," she told reporters in Werribee, west of Melbourne.
"Anybody's got an allegation of wrongdoing by me of any substance; please feel free to put it."
