The original 15 August deadline has already been extended by a week, and earlier reports suggested that the Iraqi parliament would be forced to dissolve if work on the draft constitution was not completed by the coming deadline.
Reports yesterday suggested the process was deadlocked over the role of Islam in the constitution and the division of Iraq's oil wealth.
A major stumbling bloc reportedly remains over whether to make Islam "the" main source of legislation or just "a" main source.
Compromises in the draft appear to have been found over many issues, with Kurdish and Shi'ite deputies agreeing to the name Republic of Iraq, without the words "federal" or "Islamic."
