Egyptian expatriates are lining up at polling centers in more than 100 countries to cast ballots in four days of voting for Egypt's coming presidential election.

Egypt's Foreign Ministry said Thursday that that Gulf countries and Australia are witnessing a relatively high turnout.

Egypt's presidential election will be held May 26 and 27.

Retired Field Marshal Abdel-Fattah el-Sissi, who led the ouster of Islamist President Mohammed Morsi last year, is widely expected to win the poll. He faces leftist Hamdeen Sabahi.

There are nearly 600,000 registered Egyptian voters around the world. Arab countries, especially the Gulf monarchies and the United States, have large presence of Egyptian expatriates.
