Leftist presidential candidate Hamdeen Sabahi’s campaign said its overseas representatives have witnessed violations during the expat presidential voting currently taking place in 124 countries worldwide.

Mona Amer, head of the expats committee in Sabahi's campaign, said in an official statement the violations ranged from insulting his supporters to campaigning for presidential contender and former army chief Abdel-Fattah El-Sisi inside the polling station.

Opaque ballot boxes were found in numerous polling stations, violating transparency regulations stipulated by the Presidential Electoral Committee (PEC), said another Sabahi campaign representative.

Songs and slogans were also reportedly chanted by El-Sisi voters in front of polling stations.

Amer said she reported the violations to the PEC, demanding immediate investigation.

The expatriate vote – held 15-18 May – is supervised by the diplomatic and consular corps at Egyptian embassies. An estimated 681,000 Egyptian expatriates are eligible to participate.

Meanwhile, the presidential vote to be held in Egypt is scheduled for 26-27 May.
