The Muslim Brotherhood has declared that its candidate, Mohammed Morsy, won Egypt's presidential election.
Morsy "is the first civilian, popularly elected Egyptian president," the group says on its website.
The declaration was based on returns the Brotherhood reported from 95 percent of the more than 13,000 polling stations nationwide.
The returns showed Morsy with 52 percent of the vote, his opponent former prime minister Ahmed Shafik with 48 percent.
A million votes separated the two, which a Brotherhood spokesman said the remaining votes could not overcome the difference for Shafik.
The figures were from results announced by election officials at individual counting centres, where each campaign has representatives who compile the numbers and make them public before the formal announcement.
The Brotherhood's early, partial counts proved generally accurate in last month's first round vote.
The final official result is to be announced by Thursday.
The new president was set to find out today, along with the rest of the country, what powers he will have by the ruling generals. Military and legal sources told Reuters the military council would take back legislative powers for now from a new, Islamist-dominated parliament that it has dissolved following a court ruling voiding an earlier election.
Many of the 50 million eligible voters were dismayed by an unpalatable choice between a man seen as an heir to Mubarak and the nominee of a religious party committed to reversing liberal social traditions. Some cast a ballot against both men in protest.
"I'll cross out both Morsy and Shafik because neither deserve to be president," said Saleh Ashour, 40, a shopkeeper in the middle-class Cairo neighbourhood of Dokki as he went to vote. "I want to make a statement by crossing out the two names.
"Just staying away is too passive."
