Mahmoud Abbas, the Palestinian president, has said he would call for elections in 2009 if his Fatah movement and its rival Hamas do not reconcile by the end of this year.
"If the dialogue does not begin, and if we fail, I will issue a presidential decree early next year calling for simultaneous presidential and parliamentary elections," Abbas told members of the Palestine Liberation Organization on Sunday.
Elections could be held 90 days after his decree, but there was no hint of when that might be.
Hamas immediately denounced Abbas's remarks.
"We reject the calling of the elections because it is illegal and unconstitutional," Fawzi Barhum, a Hamas spokesman, said.
Taher al-Nunu, another Hamas spokesman, said: "The law does not give any authority to the president on parliament and nobody can dissolve it before" elections are due in 2010.
Hamas won a victory in the last parliamentary elections in 2006.
Blame game
Fatah and Hamas blame each other for obstructing efforts by Egypt to heal the rift between the Palestinians, which has undermined Abbas's efforts to negotiate peace with Israel.
Abbas did not say how a single election could be held, given that Fatah and Hamas now dominate separate territories. While Fatah controls the West Bank, Hamas is in control of Gaza.
Neither did he address the probability that Hamas would refuse to take part, given that it has rejected previous election calls.
Hamas says it will not recognize Abbas as president once his four-year term expires on January 9. The group has demanded new presidential elections.
Abbas says the law gives him the right to stay in power until 2010.
Abbas said Egypt had drafted a reconciliation deal calling for a non-factional government to end the Palestinian split and prepare for new elections. But Hamas abstained from scheduled talks in Cairo earlier this month before they began.
"This is not the end of the road. We will pursue our efforts. We will continue," Abbas said in the West Bank city of Ramallah.
The Palestinian president defended himself against accusations by Hamas that he is a puppet of Israel and the United States. "I do not succumb to the Israeli-American veto. I do what is in the interest of the Palestinian people."
