Iraq's parliament, which must approve any nominee for prime minister, will meet at a date likely to be announced on Wednesday, an assembly spokesman said. Acting Speaker Adnan Pachachi was expected to set the date for parliament's next session, the spokesman was quoted as saying by Reuters on Tuesday. He did not specify its agenda, but the announcement could signal movement in intense efforts to break a deadlock on forming a new unity government four months after elections. The main Shi'ite alliance, lacking an overall majority in parliament, was expected to yield to Kurdish and Sunni pressure to drop Ibrahim al-Jaafari as its choice for prime minister. The alliance was expected to hold talks on Tuesday to make a decision on Jaafari, after one of its component parties offered to find a replacement.
