And Hussein Ibrahim, a Brotherhood member and majority leader in the legislature, insisted Sunday that parliament "has not been dissolved," according to a report from the state-run Al-Ahram news agency.
Vowing the Brotherhood won't "give it to a coup d'etat," Ibrahim said while casting his vote in Alexandria that military rulers must respect a March 30 constitutional declaration that gives only "the people" the authority to dissolve parliament.
The Supreme Council of the Armed Forces, meanwhile, issued a new constitutional declaration Sunday night detailing some powers that the new president will hold, but gave little indication it was budging on the state of parliament.
After being sworn in, the new president will set the date for parliamentary elections and can pardon and appoint government officials and ambassadors to foreign countries.
But the military leadership stated that legislative power, as well as control of the national budget, will remain in its hands until a new parliament is elected.
The Brotherhood "strongly rejected" the military declaration about parliament on its official Twitter feed. The group also said that the constitutional panel picked by parliament will hold its first meeting Monday to begin drafting a constitution, in defiance of the military council.
There's also plenty of dispute over the validity of this weekend's presidential runoff vote, which Shafik and Morsi's campaigns accusing each other of election fraud.
Turnout appeared sluggish Sunday at some polling stations in Cairo, where streets were mostly quiet despite what many Egyptians viewed as moves last week by military leaders, who have ruled the country since Mubarak was forced out in February 2011, to hold on to power. Some voters may have stayed home because of sweltering heat, officials told the state-run Al-Ahram newspaper.
As of 4 p.m. Sunday in Egypt, 40% of the nation's 50 million eligible voters had cast ballots, according to Farouk Sultan, the head of Egypt's Supreme Presidential Election Commission. In the first round of voting last month, 46% of voters participated.
Officials have reported few voting irregularities in the second round of elections, Sultan said.
