The decision by the Qarar (Decision) Alliance could prolong uncertainty in Iraq, which is still in the process of forming a government five months since a parliamentary election.

Party leader Osama al-Nujaifi, a former parliament speaker, told local media his bloc — which won 14 seats in May’s election — had abandoned the talks because ministries had been awarded to only “one bloc” representing the sect.

He was apparently referring to the other main Sunni parliamentary bloc, led by current speaker, Mohammed al-Halbousi.

Abdul Mahdi was tasked on Oct. 2 by President Barham Salih with forming the new government. According to Iraq’s constitution, he has 30 days to assemble a cabinet before Salih has to name someone else.

An independent who did not run in the May election himself, Abdul Mahdi was chosen as a compromise candidate by the two largest parliamentary blocs.
