Significance
His call comes as Prime Minister Haider al-Abadi is seeking to revive plans for wide-scale reform of government, with a new initiative to replace cabinet ministers with technocrats. Launched last August, the reforms seek to cut Iraq's bloated government and tackle rampant corruption, but are encountering tough opposition from all sectors of the political elite.
Impacts
Efforts to push through ministerial change will weaken Abadi's support base among Shia parties.
Longer term, failure on reform may see Abadi lose the backing of the Shia clergy, his strongest source of political support and legitimacy.
This would leave Abadi dependent on US support, increasing the risk of efforts to remove him and replace with a pro-Iran figure.
Without reform, Iraq's fiscal crisis will worsen and pressure for decentralised regional government will increase.
