Mohamed ElBaradei, the Nobel prize winning former head of the International Atomic Energy Agency is to be appointed Egypt's new prime minister under interim President Adly Mansour, according to a spokesman for the Constitution Party , a liberal movement founded two years ago by Mr. ElBaradei and Khaled Daoud.
Egypt's Al Ahram newspaper, online, quotes Mr. Daoud as saying that Mr. ElBaradei will be sworn in before Mr. Mansour at 9 p.m. Egyptian time, 3 p.m. ET.
Meanwhile, as many as 30 people may have been killed overnight in clashes between supporters of deposed president Mohamed Morsi and those who support his ouster by the military. But the mood of Morsi supporters on the street remains one of determination.
In front of Rabaa mosque in the area known as Nasser City, about 10,000 have gathered to hear speeches from religious leaders of the Muslim Brotherhood, the organization from which Mr. Morsi hailed.
From the stage at the base of the mosque, one can see to the west the reviewing stand where Egyptian president Anwar Sadat was assassinated in 1981 by members of Islamic Jihad, a group of extremists who had broken from the Brotherhood.
"The people want our president back," the people shouted repeatedly in unison. They are not all members of the Brotherhood, but they all believe that it was wrong for the military to step in and oust an elected president.
Ahmed Fahmy, 33, an electrical engineer, said he is not a member of the Muslim Brotherhood but that he had voted for Mr. Morsi last year in order to get rid of the remnants of the old regime of Hosni Mubarak.
"Now, just like that," he said, with a slashing chop of his hand, "they're back."
"It's Sisi that has to go," he said referring to General Abdul Fatah al-Sisi, chief of the armed forces, who announced the removal of Mr. Morsi Wednesday night, "not president Morsi."
About a kilometre north of Rabba mosque are the barracks of the Presidential Guard, where, it is believed, Mr. Morsi – and perhaps other leaders of the Brotherhood – are being held under arrest.
About 2000 young men spent much of the day here under the hot sun, pressing up against the coils of barbed wire and the glare of hundreds of soldiers.
Yesterday at this spot, at least three people were killed -- shot, apparently, by some of the soldiers.
Looking to the top of the white four-story building on the right of the entrance, one can make out two snipers positioned behind a wall of white sandbags.
The crowd is relentless in reminding the soldiers that they should not be following their orders.
"Soldiers with the rifles, are you with us or against us?" they chant.
Responding to a fiery speaker they list the many people who have, in their eyes, turned against the country: "Sisi -- traitor; Mousa -- traitor; Sabahi -- traitor," the last two being Amr Mousa, and Hamdeen Sabahi, two candidates for president last year who supported the military's move this week to oust Mr. Morsi.
"Betraying us caused blood," they called out.
