Vice-president Mekki has resigned, citing the new constitution, which does away with the post. Egyptians are voting in the second and final phase of a referendum on the country's Islamist-authored constitution. The vote on the draft charter comes amid four weeks of clashes between supporters and opponents of President Mohamed Morsi. Mekki said he intended to quit once the charter is adopted as the new constitution eliminates the role of vice president. However, statement by Mekki read on state TV, suggested that his motive might in-fact be a disagreement with the Islamist policies of President Mohammed Morsi.
