A panel of Iraqi judges has upheld the death sentence passed on Saddam Hussein.
The decision could see the ousted dictator hanged within 30 days.
Under Iraqi law a death sentence, once confirmed at appeal, should be carried out within a month.
Saddam Hussein was sentenced to death in November for his role in the execution of 148 Shias as part of a revenge campaign launched after an assassination attempt against him in the town of Dujail in 1982.
Human rights groups have argued that he has not been given a fair trial in a country torn apart by sectarian conflict that has killed tens of thousands of Iraqis.
Richard Dicker of the International Justice Program said the fact that a judicial decision was first announced by Iraq's national security advisor underlined what he called the 'political interference that marred Saddam Hussein's trial'.
Hussein is still on trial with six others for genocide against ethnic Kurds in northern Iraq in the 1980s. It is understood the trial will continue without the former Iraqi leader if he is executed.

Basra police station destroyed
In Basra, in the south, the city council in has withdrawn co-operation from UK forces after the local serious crimes unit was disbanded by troops.
More than 1,000 British troops blew up a police station run by the unit, which has been blamed for robberies and death squads.
The operation, one of the biggest British operations since the 2003 invasion, was the latest stage of a drive to stamp out renegade Shia militia elements believed to have infiltrated police operating from the compound.
