Over 39 million Egyptians cast their ballots for Sisi, a former army chief who has ruled the most populous Arab country for a decade.
The vote took place as Egypt dealt with various crises, including the Israel-Hamas war in neighbouring Gaza and the country’s worst-ever economic crisis.
Sisi was running against three other candidates, none of whom were high profile. The most prominent potential candidate ended his run complaining that his campaign had been impeded and dozens of his supporters arrested.
Runner-up Hazem Omar, who leads the Republican People’s Party, received 4.5 percent of the vote.
Next came Farid Zahran, leader of the left-leaning Egyptian Social Democratic Party, and Abdel-Sanad Yamama from the Wafd, a century-old but relatively marginal party.
Sisi is now set to serve his third – and, according to the constitution, final – term in office, starting in April.
