Mohamed Yousef el-Magariaf (Arabic: محمد يوسف المقريف‎; born 1940) is a Libyan politician who is the President of the General National Congress. In this role he is effectively Libya&#39;s de facto head of state,[1][2][3] although the powers and responsibilities of his role are somewhat poorly defined in the current interim constitution, and the position of head of government is reserved for Prime Minister Ali Zeidan.
