"Today, the National Elections Authority is here to announce that the final result of Egypt's presidential election in 2018 was a victory of Abdel-Fattah al-Sisi," said Ibrahim.
Sisi's sole rival and supporter, Moussa Mostafa Moussa, won 2.92 percent of the valid votes.
Moussa entered the election at the very last moment after first leading a re-election campaign for Sisi, saving the vote from having just one candidate.
Serious contenders to Sisi’s presidency had withdrawn, sidelined or detained.
In his victory speech, Sisi applauded Egyptians for coming out in large numbers to vote and promised to work towards improving their livelihoods.
''I pay tribute to the Egyptian people and I promise to remain in my work for Egypt's lift. I promise to work for all Egyptian people without discrimination. I would like to thank Mr. Musa Mustafa Moussa, who has fought an honorable competition in the presidential election," he said.
Sisi came to power in 2014 after he led a coup ousting the former democratically elected president, Mohamed Morsi. The military takeover was in response to the mass protests against Morsi’s one-year rule and his outlawed Muslim Brotherhood group.
Sisi had been expected to win a landslide victory in the polls. But the Egyptian leadership tried to seek a high turnout as a sign of greater popular support for the Sisi administration.
