David Cameron has said it's important he doesn't "pick Iraq's leaders" during a meeting with Nato's General Secretary Anders Fogh Rasmussen at Downing Street.
Mr Cameron told waiting journalists: "It's important that I don't pick Iraq's leaders, the people of Iraq pick their leaders, but what matters is that those leaders run that country on a non-sectarian basis, because running it on a more sectarian basis is part of the problem we are facing today."
The meeting took place as president Barack Obama prepared to announce that he is deploying about 100 Green Berets to Iraq to help train and advise Iraqi forces.
