The international peace envoy Kofi Annan says world powers have agreed on a plan calling for a transitional government for Syria. Speaking after the summit in Geneva, he
outlined
what needed to be taken place.
"The key steps in any transition include the establishment of its transitional governing body which can establish a neutral environment in which the transition can take place. That means the transitional governing body would exercise full executive powers. The transitional governing body could include members of the present government and the opposition, and other groups should be formed on the basis of mutual consent."
The US Secretary of State Hillary Clinton said after the summit that the aim of agreement was a government without President Assad.
"Assad will still have to go. He will never pass the mutual consent test. The text also makes clear that the power to govern is
vested
fully in the transitional governing body, which strips him and his regime of all authority if he and they refuse to step down and leave."
However, the Russian Foreign Minister Sergey Lavrov rejected the US interpretation of the agreement, saying there were no conditions set out on who could be in the transitional government.
"We're going to build the work for a transition and take it to a new stage, but that work will be done by the Syrians themselves. That is very clearly stated in the document it's a Syrian-led transition. We have achieved a situation where there are no prior preconditions to the transitional process and the national dialogue, and that there is no attempt to exclude any kind of group from this process."
