Iraq's election commission says the results of the first national vote since declaring victory over the Islamic State group are expected within two days.
The vote Saturday saw a record low turnout, with 44 percent of eligible voters casting ballots. No election since 2003 has had turnout below 60 percent. More than 10 million Iraqis voted.
Polling station officials blamed the low turnout on a combination of tight security measures, voter apathy and irregularities linked to a new electronic voting system.
Iraqi Prime Minister Haider al-Abadi is running to keep his post. His chief rivals are political parties with closer ties to Iran, as well as the influential cleric Muqtada al-Sadr, a staunch nationalist who campaigned against government corruption.
