Former Bosnian Serb leader Radovan Karadzic says he cannot get a fair war crimes trial at the UN Yugoslav tribunal.
Karadzic says the court is biased against him and negative publicity has destroyed any presumption of innocence.
In a filing dated August 24 and released on Tuesday, he writes that "nobody in the world believes that there is any possibility of an acquittal".
Karadzic was arrested in Serbia in July after 13 years on the run and extradited to the Hague.
He is charged with genocide for the slaughter of more than 8,000 Bosnian Muslims in Srebrenica in July 1995, when he was president of the breakaway Bosnian Serb republic.
He is scheduled to enter a plea in court Friday, or the court will enter a not guilty plea on his behalf.
