U.S. President George W. Bush and British Prime Minister Tony Blair will not set a deadline for troop withdrawal from Iraq when they meet in Washington on Thursday, the White House said on Wednesday.
"I do not believe that you're going to hear the president or the prime minister say we're going to be out in one year, two years, four years," White House spokesman Tony Snow said at a news briefing.
"I don't think you're going to get any specific prediction of troop withdrawals. I think you're going to get a restatement of general principles under which coalition troops stay or go," Snow said.
The scheduled U.S.-Briatin summit was arranged with the formation of a national unity government in Iraq, progress is being made three years after the U.S.-led invasion, despite rampant violence.
Iraqi Prime Minister Nuri al-Maliki said on Wednesday that Iraq 's army and police would be able to assume responsibility for security from U.S.-led forces across the entire country by late next year.
Bush has never offered a timetable for U.S. troops withdrawal from Iraq. But he said on Tuesday U.S. and Iraqi officials would conduct an assessment to determine what troop levels would be needed.
The United States has about 133,000 troops in Iraq.
