Naming a speaker and two deputies is the first major step towards establishing a new government, with lawmakers still trying to determine which of competing blocs had the most seats.
An alliance backing Prime Minister Haidar al-Abadi and a populist Shiite cleric has been competing with a rival bloc backed by Abadi’s predecessor Nuri al-Maliki and the Popular Mobilization Units (PMU).
After parliament met on Monday for the first time since the election, its temporary leader said it would remain in session until Tuesday. But lawmakers failed to reach a quorum on Tuesday and agreed to return in 11 days, Reuters reported.
On Sunday, lawmakers backing Abadi and al-Sadr announced they had managed to form an alliance that would give them a majority bloc in parliament.
Hours later, however, a group led by Maliki and Hadi al-Amiri, a senior member of the PMU, responded by saying it had formed its own alliance that would be the largest bloc. It said it had persuaded some lawmakers to defect from the rival bloc.
