Live Updates 2: Protesters gather for anti-Morsi demonstrations

Tens of thousands protest in Tahrir Square in opposition to President Morsi's Constitutional Declaration, with smaller opposition protests and pro-Morsi rallies nationwide

17:40 Famous football player and former parliamentary candidate for the moderate Islamist Wasat Party list, Nader El-Sayed, speaks in Tahrir Square, pointing out the large numbers of Egyptian flags displayed and commenting:
“This is because all Egyptians are here...in comparison it will be hard to see the veiled and the unveiled next to each other in tomorrow's protest [organised by the Muslim Brotherhood and Salafist parties] at Cairo University.”
17:35 Political groups in the city of Ismalia, on the Suez Canal, organised an anti-Morsi rally through the city. Marchers chanted “No to the Brotherhood constitution,” and “Down with the rule of the Brotherhood Supreme Guide.”
Among those who participated in the rally are the liberal Wafd Party and the Constitution Party, as well as the Nasserist Karama Party, the Popular Socialist Coalition and the 6 April Youth Movement.
17:30 Leading opposition figure Mohamed ElBaradei takes to Tahrir Square's main stage. Meanwhile, the news announced by stage speaker that ElBaradei, Hamdeen Sabbahi and Amr Moussa will sleep over in the square is met with applause and cheers by the 1000s-strong crowd. ##
17:15 We're back in Tahrir Square, where clashes between protesters and police are still ongoing on the periphery by Simon Bolivor Square and the Corniche.
Early this morning security forces built another concrete barricade by the US embassy, walling in the area. Khaled Mahmoud, a field doctor in the square told Ahram Online journalist Sarah Rashidi that they are in urgent need of medical supplies.
"Most of the injuries are caused by glass and stones," said Mahmoud.
Meanwhile back in Tahrir Square, Soheir, a teacher wearing the niqab (the full face veil) told an Ahram Online reporter she is against Morsi's decree and the Muslim Brotherhood.
Breaking the stereotype of ultra-conservative Muslims supporting Islamist political groups, Soheir says that she supported Mubarak-era prime minister Ahmed Shafiq in the presidential elections run-offs against Mohamed Morsi.
Her husband, Atef, agreed with her, saying that "if Morsi doesn't change the constitution then he must go."
17:10 Welcome to the second part of Ahram Online's live coverage of a day of protests against President Mohamed Morsi's constitutional declaration. You can find the first part here.
Protesters are also opposing the draft constitution, which was finalised by the controversial Constituent Assembly in the early hours of this morning. Opposition groups argue that Morsi's recent moves have shored up his own power and moved Egypt closer to dictatorship, while presidential supporters argue that the measures are temporary and necessary for Egypt's transition – and that the majority of Egyptians support the president.
So far this morning, protests have been taking place in Cairo's Tahrir Square, the Nile Delta cities of Damanhour and Mahalla, and in Alexandria, while pro-Morsi rallies have been reported in Wadi El-Gedid, Minya and Assiut in Upper Egypt.
