Egypt's third candidate in an upcoming presidential election announced he was halting his campaign and withdrawing from the race on Wednesday.
"We today announce our decision not to enter this race, and will not present our candidacy papers," the candidate, rights lawyer Khaled Ali, said at a news conference in Cairo.
The announcement came a day after Egyptian authorities detained former army chief of staff Lieutenant General Sami Anan, the only other serious potential challenger to President Abdel Fattah al-Sisi.
Ali, 45, was the first person to announce, last November, that he would run against Sisi, who led the ouster of former President Mohamed Mursi of the Muslim Brotherhood over four years ago.
