The General Assembly is the main deliberative organ of the UN and is composed of representatives of all Member States. The work of the United Nations year-round derives largely from the mandates given by the General Assembly.
The United Nations General Assembly meets the third Tuesday of every September and is made up of 193 Member States.
The newest member state is South Sudan, which was admitted as a new Member State by the United Nations General Assembly on July 14, 2011.
