The news with the referendum vote by Egyptian expatriates won't now start on Saturday leaves some space for the dialogue that President Mursi has urged with the opposition, but it isn\'t enough itself. His Vice President Mahmud Mekki now appears to suggest that the president might postpone the referendum altogether if it\'s legally possible to do so. This is the key demand of the protesters who are out in full force again near the presidential palace. Opposition leaders earlier rejected the president\'s invitation for dialogue on Saturday.____________________________________________________________________________.
