A spokesperson for publishing house Alfred A. Knopf has confirmed reports that WikiLeaks founder Julian Assange will pen his autobiography. In a recent interview with the Sunday Times, Assange explained that he is writing the book to cover growing legal costs. “I don’t want to write this book, but I have to,” he told the Times. “I have already spent 200,000 pounds for legal costs and I need to defend myself and to keep WikiLeaks afloat.”

Assange went on to share that the book deal will bring in more than $1 million, although a Knopf spokesman has declined to comment on that figure. Assange previously told reporters that most of WikiLeaks’ money goes toward legal expenses and fighting off technical attacks. Assange is currently free on bail in England, and is fighting extradition to Sweden, where he faces allegations of sex crimes.

While no publication date has been given at this time, a Knopf spokesman says that Assange is due to deliver the manuscript sometime in 2011. The title has not yet been made public.
