Scores of protesters attacked Governor Nawfal Hammadi al-Sultan's car on Friday, forcing him to leave the site of the accident. The crowd threw stones and shoes at the vehicle, which sped off, hitting two people, one of whom was taken to hospital.
Prime Minister Adel Abdul-Mahdi on Saturday formally asked parliament to remove Sultan. Iraqi law gives the federal parliament the right to sack provincial governors based on the suggestion of the prime minister.
Parliament also voted to sack Sultan’s two deputies, in line with Abdul-Mahdi’s request.
The governor can appeal the decision at court. He has not commented on the vote yet.
In his letter to parliament, Abdul-Mahdi accused Sultan of negligence and dereliction of duty, and said there was evidence he had been misusing public funds and abusing power.
Protesters blamed negligence by the local government for the accident. The boat had been loaded five times its capacity, according to a local official.
