Polling stations have opened in Egypt for today's presidential election runoff. The second-round vote pits Muslim Brotherhood candidate - Mohamed Morsi - against Ahmed Shafiq, a former prime minister in the toppled government of Hosni Mubarak. Voters are divided between those who fear a return to the old system and others who fear the Brotherhood will use religion to stifle personal freedoms. The runoff comes two days after Egypt's Supreme Court dissolved the Islamist-dominated parliament - ruling that last year's parliamentary elections were invalid. The court also overturned a law that barred senior members of the Mubarak government from running for public office. RFI spoke to Mohamed Mohieddin, a sociologist from Menoufiya University, whose took part in last year's Egyptian uprising.
