BAGHDAD — As differences between Iraqi Prime Minister Haider al-Abadi and some pro-Iran factions of the Popular Mobilization Units escalate, these factions are trying not only to dismiss Abadi but also to change the system of government from a parliamentary to a presidential one. Currently, the prime minister holds executive power.

Several of the factions demanded Abadi's resignation Sept. 8 after parliament held an emergency session to address deadly protests in Basra. Citizens are rioting over, among other things, a lack of basic public services that has resulted in tens of thousands of people flooding hospitals after consuming water that is highly polluted and salinated. Abadi is visiting Basra Sept. 10.

Iraq's political parties have failed to form a new Cabinet; they are still arguing over which coalition holds the majority of parliament seats. Abadi, who leads one of the coalitions, is seeking another term as prime minister.

Calls to transform the type of government are being met with a series of substantive and legal obstacles, which experts say makes it difficult to imagine this scenario playing out anytime soon. However, some prominent political forces confirm that this goal is one of their priorities.
