In an interview with Al Jazeera from London, Sabah al-Mukhtar, a political analyst said, he doubts that a federal system could work in Iraq. <br /><br />"I don't think it's going to happen," Mukhtar said. "The idea of federation cannot be based on sectarian or ethnicity. It's usually a geographical situation".<br /><br />Mukhtar also said that there is "no effective" government in Iraq that could solve the recent sectarian violence. <br /><br />"The dictatorship of Saddam Hussein has been replaced by the dictatorship of Maliki," he said, referring to Iraqi President Nouri al-Maliki.
