Polling stations have opened in Egypt in the second and final round of a referendum on a new constitution. It was drafted by an assembly which the opposition says is polarising the nation.
After a first round vote last week which unofficial results showed as 57 per cent approval of the constitution, polls opened again at 8am local time (6am GMT).
Polls are scheduled to close at 7pm (5pm GMT) but could be kept open longer as they were last week.
The opposition said voting in the first round was littered with abuses. Officials overseeing the poll have said there was no major irregularities.
