Voting is under way in Ghana's presidential election in what analysts say is a tight race between President John Mahama and Veteran opposition leader Nana Akufo Addo.
 
All seven candidates have pledged to keep the process peaceful but an opposition supporter died when a rally turned violent on Monday.
 
The campaign has been dominated by the faltering state of Ghana's economy and the issue of corruption.

Over 15 million Ghanaians are voting in presidential and parliamentary elections.
 
Long queues had already formed at polling stations across the country when voting began at 7 a.m with some voters arriving shortly after midnight.
 
There are seven candidates vying to be president including incumbent president John Dramani Mahama but only Nana Akufo Addo of the main opposition party stands a serious chance of causing an upset.
 
Ghanaians will also be  275 members of parliament from the 10 regions of the country.

 A run-off will be held later in the month if neither of the two main candidates secures more than 50 per cent of the votes.
 
Results are expected within three days.
