TUNIS - Kais Saied, a political outsider and retired law professor, was sworn in as Tunisian president on Wednesday after he won a landslide victory in this month's election.

Saied's victory delivered a heavy blow to a governing elite accused of failing to improve living standards or end corruption since the 2011 revolution that introduced democracy and ushered in the North African country.
