During a nationwide referendum, voters were asked to consider a series of proposed constitutional amendments.
If enforced the amendments would extend presidential term limits from four to six years, increase the role of the Egyptian military, and grant the president more control over the judiciary.
The amendments allow a leader to remain in office for two terms but include an article specific to the current president, Abdel Fattah Al-Sisi.
He was elected in 2014 and re-elected last year.
