The Brotherhood accused the government of
blocking supporters from voting [Reuters]
Safwat el-Sherif, the NDP's secretary-general, said: "This is due to the confidence the people have showed in the party's candidates."
The Muslim Brotherhood conceded defeat, but it also denounced the results as a setback for democracy.
The Brotherhood on Monday accused the government of blocking opposition supporters from voting in some polling stations, charges the government denied.
A man was killed when supporters of rival candidates outside a polling station clashed in the northern Nile Delta region as the authorities kept security tight across the country.
And limited judicial monitoring raised doubts over the fairness of the election process.
The election was also a test of a new law passed by the government of Hosni Mubarak, the president, banning the use of religious symbols and slogans, seen as an attempt to keep the Brotherhood out of mainstream politics.
