Mr Slobodan Milosevic's lawyers claim he will be handed over to the UN war crimes tribunal soon after a law allowing his extradition is adopted.
The former Yugoslav president was arrested on April 1st at his Belgrade villa.
He has since been in detention in Belgrade's Central Prison pending an investigation into allegations of corruption and abuse of power during his 13-year rule.
But The Hague-based tribunal in the Netherlands wants him tried for alleged war crimes against ethnic Albanians in Kosovo in 1999.
The Vecernje Novostinewspaper, which is close to the Serbian pro-democracy coalition, said its officials have agreed to hand Mr Milosevic over to The Hague "urgently" after the law is passed.
Mr Zdenko Tomovic, one of Milosevic's lawyers, claimed a helicopter was ready to transport Mr Milosevic from his jail and hand him over to the tribunal authorities.
In Berlin today the chief war crimes prosecutor renewed her appeal for Yugoslavia to hand Mr Milosevic over to the UN tribunal and for fresh international pressure to make it happen.
"I am waiting for Milosevic's transfer," Ms Carla Del Ponte said after talks with German Foreign Minister Mr Joschka Fischer. "The international community must help me in order for Milosevic to appear in The Hague. Of course I hope he will be brought there very quickly."
But Yugoslavia's legal procedure to hand Mr Milosevic over to the tribunal has hit a snag.
A parliament session planned to discuss the law that would allow Mr Milosevic's extradition has been postponed for a day to give time for a last-ditch compromise between Serbia's pro-democracy forces with the former president's Montenegrin allies who are opposed to the Bill.
