The protests have swelled in size in the past four days, posing the greatest threat to Egypt’s military leaders since Hosni Mubarak’s ousting last February.

The military council has promised to hand over power to a civilian government no later than July 1, 2012, according to state news agency MENA. That date is significantly earlier than expected. The AP reports that Egypt’s military council is even floating the idea of a referendum on an immediate power transfer.
