Visually impaired Nigerians set to vote
Nigeria's National Electoral Commission has launched a braille ballot guide, estimated to have cost the country at least $100,000, which allows visually impaired voters to enjoy the secrecy of their ballot as they will no longer be led by others to make their choice on voting day. David Okon is a member of the Nigerian blind association.
