CAIRO — Egyptians voted for a second day on Sunday in a referendum on proposed constitutional amendments aimed at cementing the rule of President Abdel Fattah El-Sisi.

Sisi is widely expected to win backing for changes making it possible for him to stay in power until 2030, boosting his control over the judiciary and giving the military even greater influence in political life.

Egyptian media outlets, tightly controlled by the state, have carried images of packed voting stations, while dissenting voices from the opposition and rights groups against the measures have been largely restricted to the internet.

Some voters say their employers have encouraged them to vote, while others say they have received food coupons from unidentified people.

In their initial report on the first day of the nationwide electoral process, an international observer team said “there were no hurdles to voting”.

The three-day referendum bucks the trend of North Africa’s renewed uprisings, in which mass pro-democracy protests this month swept away veteran presidents in Algeria and Sudan.

Former defense minister Sisi took power in 2013 and was elected president in 2014 after leading the army’s overthrow of Islamist president Mohamed Morsi.

He was re-elected for another four-year term in 2018 with more than 97 percent of the vote.

The proposed constitutional changes would allow him to extend his current term by two years and to run for another six-year term.

Since Sisi took power, rights campaigners have regularly accused his government of abuses including mass trials and torture, as well as a clampdown on opposition and the press.

Human Rights Watch has slammed the proposed changes, saying they would “entrench repression”.

In a statement Saturday, the New York-based watchdog criticized the “grossly unfree, rights-abusive environment” of the vote.

Troops and police were deployed in strength across Cairo, although the interior ministry declined to give any nationwide figures.

Egypt is battling a hardened insurgency based in the Sinai Peninsula that has seen attacks in Cairo and other cities.

Sisi has argued that he needs longer to complete the job of restoring security and stability after the turmoil that followed the overthrow of veteran autocrat Hosni Mubarak in the Arab Spring of 2011.

Supporters of the amendments say they will help ensure Egypt’s political stability, security and economic development.

Some 61 million of Egypt’s nearly 100 million population are eligible to vote. The results are expected to be announced on April 27. — Agencies
