CAIRO (REUTERS) - Egyptian President Abdel Fattah al-Sisi is on course for a landslide election victory although there was little sign he had achieved the high turnout he sought, according to early estimates after polls closed in a three-day election.

Some voters said they had received payments and other inducements to cast their ballots.

But with some private television stations reporting that he could achieve a vote share of 95 percent or more, Sisi issued a defiant statement expressing pride at the way Egyptians had conducted themselves during the election.

"The voice of the Egyptian masses will undoubtedly bear witness to the fact that our nation's will imposes itself with a force that knows no weakness," Sisi said on Twitter.

"The scenes of Egyptians at polling stations will remain a point of pride and honour for me and undoubted proof of the greatness of our nation that has offered the blood of its greatest sons so that we can together cross into the future."

Preliminary results show Sisi is leading with 21.5 million votes, state-owned newspaper Akhbar el-Youm reported on Thursday (March 29).

Sisi is running almost unchallenged after the other serious candidates were either arrested or intimidated and he is widely expected to win a second four-year term. The electoral commission issued a last-minute call for people to vote, hoping to boost the turnout figure.

His only challenger, Moussa Mostafa Moussa, a Sisi supporter, garnered 721,000 votes, the newspaper reported. There are about 60 million eligible voters in Egypt.

Voting was extended by one hour, the state news agency MENA reported.

TURNOUT

On the first two days of voting, turnout was about 21 per cent, according to two sources monitoring the election.

A Western diplomat said that late on Tuesday, turnout was between 15 and 20 percent, with around 30 per cent in some centres on Wednesday.

In the city of Alexandria, an election observer said three polling stations had turnouts of 26.6, 32, and 33.75 percent by late Wednesday afternoon.

At the last election in 2014, turnout was 47 per cent, although Sisi won 97 per cent of the overall vote. Official results are due on April 2.

Sisi said he wanted more opponents to stand, and insisted he had nothing to do with opposition candidates pulling out. The election commission had pledged the vote would be free and fair.

In Cairo, some voters found it hard to voice enthusiasm.

Mostafa Abdel Kader, a 35-year-old delivery man, expressed anger at some Sisi loyalists distributing food to persuade people to cast their ballots, saying he would not vote "for a box of food".

Hussain al-Sayed, a 53-year-old tailor, did vote, although without much enthusiasm. "Sisi will win anyway, there is no one else."

Sisi, who led the military overthrow of freely elected Islamist President Mohamed Mursi in 2013, has promised security and stability and to revive the economy after unrest that followed a 2011 popular uprising.

INCENTIVES

Some voters interviewed by Reuters over the first two days of polling said they had been offered money, boxes of food, and services to cast their ballots.

"I just went to vote so I can dip my finger in the paint and took the 50 pounds (S$3.70)," a woman in Cairo's working-class Ward estate said, declining to give her name.

Another group of women, who also declined to be named, said they had been promised bags of food containing rice and vegetable oil in exchange for votes.

The women did not say who exactly had given them money or bags of goods.

Managers at a government financial institution gave employees half of Monday off and ordered them to vote, one employee told Reuters. Employees at the institution were told to "not come back without ink on their fingers" and had their hands inspected the next day, the employee said.

Asked for comment, the presidency spokesman said this was not a matter for the presidency to address and referred Reuters to the National Election Commission and spokespeople for the presidential campaigns.

Officials at the election commission and the government's foreign press centre did not respond to calls and Whatsapp messages requesting comment.

The national election commission had said those who did not vote could be fined 500 Egyptian pounds.

Some people needed no inducement to vote. Noha al-Nemr, in Cairo's middle-class Mohandiseen district, said: "I voted for Sisi of course, because it's enough that because of him, my family and I live in safety - even if there's hardship."
