Senegal's new president Macky Sall was sworn in on Monday after a crushing poll victory over outgoing leader Abdoulaye Wade and a transfer of power hailed as an example of democracy in Africa.

"I swear to faithfully fulfil the office of president ... to observe and enforce the constitution, to devote all my efforts to defending constitutional institutions, territorial integrity and national independence," Sall said as he took the oath, his right hand raised.

Some 2,000 people attended the ceremony in the gardens of a large hotel in the seaside capital, including 11 African heads of state from countries such as Liberia, Ivory Coast, Gambia, Burkina Faso, Guinea and Sierra Leone.
