"The parliament speaker has decided to postpone the session to Monday, Nov. 12, for more consultation and agreement over the president, who symbolizes the country's unity," a government statement said.

Under the constitution, Lebanese President Emile Lahoud must step down by Nov. 23 but rival parties have been unable to reach consensus on a replacement, the Alalam Satellite TV network reported.

Lebanese Prime Minister Fouad Siniora is considered an ally by the United States and Saudi Arabia, while opposition parties, including Hezbollah, claim he is a U.S. puppet, the report said.

Opposition parties boycotted parliament on Sept. 25, meaning the ruling coalition didn't have a two-thirds quorum and a presidential vote was postponed, the network said.
