Mr Olmert wants to draw up a document of understanding that will serve as a framework agreement they can take to Washington next month, officials say. However, the Palestinians have said they will not sign a partial deal.

Mr Olmert has promised to resign after his Kadima party chooses a new leader in a primary election on September 17.

The prime minister announced his intention in July following months of pressure resulting from the opening of a police inquiry into money he received from a US-Israeli businessman.
