Iraqi state television says Iraq's Nouri al-Maliki has given up his post as prime minister to Haider al-Abadi.
The Iraqi television network said al-Maliki has "relinquished the post of prime minister." It did not elaborate.
The announcement comes ahead of an address al-Maliki is due to make later Thursday evening, according to the government.
Iraq's President Fouad Massoum named al-Abadi on Monday to form the next government, but al-Maliki had until now refused to step aside.
