LONDON (Agencies) - Struggling to pay his mounting legal bills and keep WikiLeaks afloat, Julian Assange has said he has signed contracts worth $1.5 million for penning his autobiography. Assange, whose whistleblowing website has provoked US rage by releasing secret diplomatic documents, said the money will help him to defend himself against the sexual assault claims made by two women in Sweden, which he denies. I dont want to write this book, but I have to, he told The Sunday Times in an interview. I have already spent 200,000 pounds for legal costs and I need to defend myself and to keep WikiLeaks afloat. The 39-year-old Australian said he will receive $800,000 from a US publisher Alfred Knopf and $500,000 from a British deal with Canongate. The total sum from the deals, including those with other markets, will reach over $1.5m. The WikiLeaks founder was released on bail by a British court last week and vowed that he would continue his work. Assange has been staying at a friends Norfolk mansion in eastern England since his release from jail December 16 on strict bail conditions that include reporting to police daily and wearing an electronic tag. World leaders and diplomats have downplayed the impact of the leak of more than 250,000 confidential US diplomatic cables by the WikiLeaks site. Assange, who is on bail while fighting extradition to Sweden to face allegations of sexual assault brought by two Swedish women, claimed that he had been a victim of revolutionary feminism. I fell into a hornets nest of revolutionary feminism, he alleged. The lawyer of the two women who have accused Mr Assange of sexual misconduct hit back saying that he was spreading false rumours to smear his clients. He denied allegations made by Assanges legal team that they were CIA pawns and pointed out that, on the contrary, they were supporters of WikiLeaks. He has been spreading false rumours (that) he knows are untrue, said the lawyer Claes Borgstrom. Assange said he was determined to avoid extradition to Sweden as he feared that Swedish authorities would hand him over to the Americans who could put me in prison and throw away the key. The book deal was described as new years gift to Assange and WikiLeaks whose finances have been hit after credit-card companies, Visa and MasterCard, and the internet payment firm PayPal blocked donations to it under American pressure, he alleges.
