Mexico on Sunday called for an overhaul of the United Nations Security Council, envisaging more member countries across a wider geographical swathe, as the government steps up efforts to raise its profile on the global stage. In a statement, Mexico's foreign ministry said it wanted the 10 temporary members to grow to 26, with six members coming from Africa, five from Asia, four from Latin America and the Caribbean, five from both Western and Eastern Europe, and one from small developing nations.
