CAIRO (Update 2) -Preliminary indications show a majority of Egyptians who voted in a referendum backed constitutional changes that will allow Egypt's military rulers to move swiftly to elections, a judicial source said on Sunday. A parliamentary vote, if the referendum result is confirmed, could now take place as early as September. "The preliminary indication of the result a few hours before the official announcement is that turn out nears 60 per cent and 70 per cent voted 'yes', 4 per cent were invalid votes and 26 per cent said 'no'," a judiciary source told Reuters. Votes have been counted in a referendum on proposed constitutional changes that will determine how quickly Egypt can hold elections after Hosni Mubarak was toppled, the judicial oversight body said on Sunday. Approval of the amendments will allow Egypt's military rulers to move along the path they have charted towards parliamentary and presidential elections that will allow them to hand power back to a civilian, elected government. The military has said a parliamentary election could happen as early as September with a presidential election after that. Rejection of the amendments would force a change in plan that will possibly delay the elections. "All the polling stations in Cairo and the governorates ... have finished the voting and the counting process and all documents and results have been delivered," Mohammed Ahmed Attiyah, the head of the supreme judicial committee supervising the voting, said in a statement. He did not indicate what the result was or say when it would be announced. Independent election monitors said they expected results later on Sunday. The vote, designed to usher in free legislative and presidential elections, has divided the country's reform movement between those who favour the amendments and others who demand that the constitution be completely rewritten.
