Adli Mansou has been sworn in as interim president in Egypt after a dramatic 24 hours during which the army staged a military coup against the country's first democratically elected leader, Mohamed Morsi.
Mansour has been appointed head of state under an army transition plan. Earlier today he took his oath as head of the supreme constitutional court.
Mansour has served for many years in Egypt's State Council, which provides legal advice to the government. In 1992 he was appointed to the Supreme Constitutional Court - a body that had remained largely unreformed since Morsi was elected.
The court clashed with Morsi on a number of issues, including changes to the constitution that increased presidential power.
Morsi is being held by authorities and is currently under house arrest at the Presidential guards club, according to the Muslim Brotherhood.
Mansour's role will be to oversee a revision of the constitution, as well as fresh parliamentary and presidential elections.
Last night hundreds of thousands of people took to the streets to celebrate the coup in Cairo and Alexandria, but there were clashes and 14 people died, Reuters reports.
