John Dramani Mahama was sworn in for a second term as Ghana's president on Tuesday at a ceremony in the capital Accra, pledging to overcome public discontent by boosting the economy and creating much-needed jobs.

Ghana on Tuesday swore in president-elect John Mahama in the capital Accra before some 20 regional leaders as he promises to lift the West African gold and cocoa producer out of the doldrums.

But Mahama will be under pressure to deliver quickly on campaign promises to curb high youth unemployment and root out entrenched corruption - issues that have fueled distrust in Ghana's political system.
