Thousands of Egyptians camped out on Saturday night in Cairo's Tahrir Square.
They're vowing to stay until the country's first elected president is officially named on Sunday
The protesters, many of them supporters of Islamic Brotherhood candidate Mohamed Morsy, have gathered here for four days in a row.
The ruling military council's removal of many of the new president's powers has angered many.

"I need the protest to continue until it achieves all the demands of the revolution. The upcoming president has no authority, so how can he rule? He should come into office with complete powers."
In another part of Cairo supporters of presidential candidate Ahmed Shafik take to the streets to show their backing.
Shafik, the last prime minister under deposed President Hosni Mubarak, is, like his rival, claiming to have won.
Whoever emerges the victor in Egypt's first ever democratic election, there's likely to be some kind of backlash.
