The main Sunni political faction in Iraq says it is ending a boycott of parliament, paving the way for talks with other groups.
Iraqiyya walked out over an arrest warrant for Vice-President Tariq al-Hashemi.
Mr Hashemi is accused of running death squads during the insurgency. A warrant for his arrest was issued on 19 December. He is in hiding in Kurdish northern Iraq.
Iraqiya describes the move to end the boycott as a gesture of goodwill.
The party won the largest number of seats in elections in March 2010, but was unable to form a government.
