Abdel Fattah al-Sisi has secured a third term as Egypt's president winning 89.6% of the vote, the National Elections Authority said.

Mr 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.

Mr Sisi was first elected president in 2014, and was returned to office in 2018, both times with 97% of the vote.

The constitution was amended in 2019, extending the presidential term to six years from four, and allowing him to stand for a third term.

He will remain in power until 2030 after an election overshadowed by a domestic economic crisis and the war in Gaza, a territory that borders Egypt's Sinai peninsula.

Some voters said the eruption of conflict in Gaza had encouraged them to vote for Mr Sisi, who has long presented himself as a source stability in a volatile region.

It is an argument that has also proved effective with Gulf and Western allies providing financial support to his government.

Voting in Egypt was held over three days from 10-12 December with the state and tightly controlled domestic media pushing hard to boost turnout above the 41% recorded the last presidential election in 2018.

Mr Sisi, a former general, has overseen a sweeping crackdown on dissent across the political spectrum since leading the 2013 overthrow of Egypt's first democratically elected leader, Mohamed Mursi of the Muslim Brotherhood.

Authorities have sought to address criticism of Egypt's human rights record with steps including by opening a national dialogue and releasing some prominent prisoners, but critics dismissed these moves as largely cosmetic.

Many Egyptians expressed indifference about the election, saying the result was a foregone conclusion.

Reporters who covered the vote in Cairo, Giza, Suez and the Sinai Peninsula witnessed people being bussed to some polling stations and waiting outside them waving national flags or banners as patriotic music played.

Other stations appeared quiet.

Bags of flour, rice and other basic commodities were also handed out to people who voted in Giza.

Egypt's state media body said the vote was a step towards political pluralism and authorities denied violations of electoral rules.
