WikiLeaks founder Julian Assange has levelled a question at Prime Minister Julia Gillard via video link from house arrest in the UK, asking if she swapped information about citizens with foreign powers.
Assange, under house arrest in London, made a surprise appearance on video during the ABC's Q&A program on Monday to ask whether Ms Gillard had swapped information about Australians, particularly those who work at WikiLeaks.
Ms Gillard, just back from a trip to the United States, rejected the claim.
"I honestly don't know what he's talking about," she said, adding that no-one in the US had asked her about Mr Assange.
"So I'm afraid I can't help him with a full and frank exchange about people who work with WikiLeaks.
"To my knowledge it hasn't happened."
But she conceded that the exchange of information between countries happened often, in cases relating to drug or people trafficking.
