Cairo — Two more potential presidential election candidates in Egypt withdrew on Saturday, leaving the way clear for incumbent Abdel Fattah El-Sisi to stand unopposed.

Only Sisi, in power since 2014, has so far officially announced his candidacy in the election for which voting is set for March 26.

Nominations for candidates remain open until Monday.

Zamalek football club boss Mortada Mansour announced on Facebook on Saturday that he will not be a candidate, despite previously saying that he would.

The head of the old liberal El-Wafd party, Sayed El-Badawi, also withdrew on Saturday and announced his backing for Sisi.

On Wednesday, rights lawyer Khaled Ali, seen as the last real challenger to Sisi, stepped aside.

The National Election Authority announced on Jan. 8 that the deadline for applications would be Jan. 29.

Under Egyptian law, presidential hopefuls must collect endorsements from at least 20 lawmakers, or at least 25,000 registered voters, with a minimum of 1,000 signatures from each of at least 15 provinces.

Since December, one by one, all of the president's likely challengers have either ruled themselves out of the race or been sentenced to time in prison.

Sisi on Wednesday officially submitted his application to stand for a second four-year term. — Agencies
