Profiles of the two candidates competing in Egypt's presidential runoff Saturday and Sunday.

AHMED SHAFIQ

The former Air Force commander and civil aviation minister was Mubarak's last prime minister and was dumped in the face of protests after the president's ouster. Shafiq, 70, scores points by presenting himself as a strongman who will stabilize the country, promising to restore law and order within 24 hours of taking office. His campaign for the runoff has focused on warning against the Muslim Brotherhood, drawing on the fear among many Egyptians of its rising power and what they see as its drive to dominate the state and change their lifestyle with stricter Islamic rules. Opponents view Shafiq as the military's favorite.

In the first round, Shafiq came in second, winning a surprisingly high 5.3 million votes or nearly 24 percent of the total.

MOHAMMED MORSI

The candidate of the Muslim Brotherhood, Egypt's strongest political movement, was educated as an engineer in southern California.
