The National Alliance to Support Legitimacy (NASL) has called on supporters of ousted president Mohamed Morsi to launch a wave of protests starting Friday, to be escalated on Sunday's presidential inauguration ceremony.
"We will continue the wave of protests that initially started on 3 July," declared the NASL statement released late on Wednesday.
The Islamist coalition stressed that the protests were to begin on Friday, intensify during the official inauguration of President-elect Abdel-Fattah El-Sisi on Sunday 8 June and persist along the rest of the week.
Meanwhile, the government has declared Sunday a day off for the public sector, as announced on state TV. For schools and universities, however, Sunday is a normal working day.
Official results of the presidential elections were announced by the Presidential Elections Commission (PEC) late on Tuesday declaring El-Sisi Egypt's next president by confirming that he won 23.78 million votes (96.91 percent of the valid ballots).
El-Sisi's sole contender, leftist politician Hamdeen Sabahi, collected a modest 757,511 of the votes (3.1 percent).
According to the PEC's Judge Anwar El-Assi, 25,578,233 voted in the elections, a turnout of 47.5 percent.
Nevertheless, the alliance claimed that "the low turnout" at the presidential poll evidenced the Egyptian people's will to reject what it described as the "military coup" that ousted Morsi.
They had also argued a "low turnout" of the expat voting – which took place from 15-18 May – declaring it null and void.
However, again contrary to NASL assertions, the number of expats who voted in the 2014 poll exceeded that in the 2012 presidential elections that brought Morsi to power.
The Muslim Brotherhood-led coalition still insists Morsi is Egypt's legitimate president. The group describes Morsi – who currently faces multiple trials on charges including murder and espionage – as the "kidnapped president".
El-Sisi, in his former capacity as the country's defence minister, had led Morsi's removal following mass protests against the Islamist president's troubled one-year rule.
Despite the dwindling numbers of Morsi supporters in street protests – now mainly confined to some Egyptian universities – the NASL consistently claims the momentum of its demonstrations remains undeterred.
