Islamist Mohammed Morsi has been sworn in before Egypt's highest court as the country's first freely elected president, succeeding Hosni Mubarak who was ousted 16 months ago.
Morsi, the Arab world's first freely elected Islamist president, became Egypt's fifth head of state since the overthrow of the monarchy some 60 years ago.
He took the oath on Saturday before the Supreme Constitutional Court in their Nile-side courthouse built to resemble an ancient Egyptian temple.
Morsi has vowed to reclaim presidential powers stripped from his office by the military council that took over after Mubarak's overthrow.
But by agreeing to take the oath before the court, rather than before parliament as is customary, he is bowing to the military's will in an indication that the contest for power will continue.
