Tahrir Square filled with demonstrators overnight Thursday, voicing support for Islamist presidential candidate Mohamed Morsy.<br/> <br />They say his rival in the run-off, Mubarak's last prime minister Ahmed Shafik, can only win using fraudulent methods which were common practice under the old regime.<br/> <br />A war of words has been raging since polls closed Monday with both camps claiming victory.<br/> <br />Shafik told supporters he was confident that the Electoral Commission would declare him the winner.<br/> <br />But there is widespread concern that the interim army rulers, who recently dissolved parliament and changed constitutional arrangements, are attempting to retain power whoever is declared the winner.<br/> <br />This man rejects the constitutional decree and says it, like the military council, is illegitimate.<br/> <br />The Electoral Commission plans to announce the results of the presidential run-off on Saturday.<br/> <br />Lily Grimes, Reuters
