Authorities in Gabon say voters have overwhelmingly approved a new constitution more than one year after mutinous soldiers overthrew the country’s longtime president and seized power in the oil-rich Central African nation.

The constitutional change would also require presidential candidates to be exclusively Gabonese, with at least one Gabon- born parent and have a Gabonese spouse. The criterion disqualifies ousted ruler Ali Bongo Ondimba,

The new constitution would introduce two-term limits on the presidency, remove the position of prime minister and recognise French as Gabon's working language. The presidential term would be set at seven years.
