There are also calls, still undeveloped, for greater unity ahead of the presidential run-off election on June 16-17. Such appeals range from demanding an immediate transfer of power to a coalition of revolutionary presidential candidates (although the mechanism is vague) to the formation of a united presidential front in the runoff, with Mohamed Morsi of the Muslim Brothers (MB) as President and left-leaning Nasserist Hamadin Sabahi and liberal-leaning moderate-Islamist Abdel Moneim Aboul Fotouh as Vice-Presidents.
