Egypt readies itself for official confirmation of who will become president, the Brotherhood's candidate Mohamed Mursi or Mubarak-era premier Ahmed Shafiq. Follow Ahram Online's blow-by-blow coverage 15:14 Cairo's eastern district of Nasr City, a frequent rallying point for Shafiq supporters, is playing host to a crowd of just a few dozen. Thousands gathered there on Saturday, chanting slogans against the Brotherhood and in favour of Ahmed Shafiq, bringing traffic to a halt. 15:12 Egyptian state TV says announcement of results will be delayed 30 minutes. 15:08 One protester in Tahrir Square tells an Ahram Online reporter of his fears that Shafiq will win. "If the votes are fair, why are they afraid to announce them?" asks Hanan Mahrous, a 23-year old graduate student. Mahrous voted for Hamdeen Sabbahi in the initial vote then Mursi in the second round. “How could anybody vote for someone whose role model is Mubarak?" she asks. "The Egyptian law copies French law in everything . Why did it not copy the presidential elections system there and have early results?" 15:01 Members of the Egypt's presidential electoral commission arrive at the committee's headquarters in Nasr City. The announcement is to be made in a hall already crowded with Egyptian and international media. The result is expected in a few minutes. 14:59 Ahram Online reporter Bel Trew describes scene around Tahrir Square where thousands of mainly Mursi supporters are demonstrating. She says some supporters are riding around the square on the back of fun-buses, blaring music that proclaims "we are one hand". 14:58The Rafah crossing between Egypt and the Gaza Strip has been closed at the order of Egyptian authorities, according to an official from Hamas which governs the besieged territory. Egyptian authorities are yet to make a statement on the matter. 14:55 Former presidential candidate Abdel Moneim Abul-Fotouh will hold a press conference on Monday to comment on the election results, his campaign managers say. 14:53 The headquarters of Egypt's electoral commission in Nasr City are stepping up security ahead of the 3pm announcement. Security barriers have been erected around the premises, while streets surrounding the bulding have been closed and no vehicles allowed in. Journalists have been granted access on foot but are being extensively searched in an apparent attempt to prevent supporters of either candidate from causing trouble. 14:45 The Muslim Brotherhood is saying it won't leave Cairo's Tahrir Square, even if its candidate Mohamed Mursi is declared president. Speaking to the local Dream TV channel on Sunday, Hassan El-Barnes - a leading member of the Brotherhood and a former MP for its Freedom and Justice Party - said the sit-in will continue. "The protesters in Tahrir have demands, most importantly cancelling the constitutional addendum that makes the SCAF a state above the state and turns Egypt from a civilian state to a military one which limits the president's powers," El-Barnes said in an interview on 'Sabah Dream'. The Muslim Brotherhood's official Twitter account posted the following a short while ago: "Our protests will remain peaceful and we will not leave #Tahrir until the peoples' demands are met, including recent #SCAF decrees." 14:20 Dozens of Mursi supporters marching from the central Cairo district of Abdeen have arrived in Tahir Square. They're shouting "Legitimacy is in Tahrir … revolutionaries are in Parliament", and "Shafiq tell the truth, is Mursi your president or not?" Carrying the Egyptian flag and pictures of the Brotherhood candidate, the protesters are calling for the implementation of the Political Disenfranchisement Law which would have eliminated Ahmed Shafiq from the presidential race. They're also rejecting the 19 June constitutional addendum issued by the ruling military as well as last week's dissolution of parliament and justice ministry decree allowing military police to arrest civilians. 14:12 The government of current Egyptian premier Kamal El-Ganzouri will resign immediately if Mohamed Mursi is announced president, says Ahram's Arabic-language news site, quoting "government sources." But should Ahmed Shafiq prove victorious the resignation will be postponed, the report claims. Ganzouri's government was appointed by the Supreme Council of Armed Forces (SCAF) in December 2011. According to the constitutional declaration, it will be relieved of responsibility on 30 June. There's less than an hour to go before Egypt is due to hear the official results of the country's first post-Mubarak presidential elections. The Supreme Presidential Electoral Commission (SPEC) announced Saturday that it will declare the new president at 3pm today. The winner will then be inaugurated on 30 June. Tensions are riding high and security forces have permeated the capital's streets as these polarising elections that pitted Muslim Brotherhood candidate Mohamed Mursi against Mubarak's last premier, Ahmed Shafiq, draw to a close. There are widespread rumours that supporters of the two candidates may clash or react violently to the outcome. The Ministry of Interior has said it has put its forces on a heightened state of alert. Government institutions, schools and several embassies have either closed entirely or have let their employees return home early before the results are announced. Thousands have gathered in central Cairo's Tahrir Square over the last week, the majority of them Mursi supporters, protesting new changes to the country's constitution and the dissolution of parliament. Shafiq supporters, meanwhile, made their voices heard in the eastern Cairo district of Nasr City on Saturday. Blocking a main road for hours, they protested against the Brotherhood and declared support for their candidate. Follow Ahram Online for the latest developments.
