Ghana's main opposition candidate Nana Akufo-Addo has told the BBC he is confident of winning Wednesday presidential election.

Mr Addo, a third-time candidate, is up against President John Dramani Mahama and five other candidates.

In an interview with the BBC's Akwasi Sarpong, he said voters will give him a chance this time around because he represents the best option:

The circumstances of the country are such that I think the ruling party has run out of credit. The performance has been poor. The management of the economy has been poor. And it has meant a lot of difficulties for the Ghanaian people. Lot of people don't have work. Income level is very fragile. The cost of living is very high. There is a great deal of despondency across the country."

Mr Akufo-Addo, the flagbrearer of the New Patriotic Party, praised the electoral commission's preparations for the poll:

If [the arrangements] are carried out and respected, they should give us a credible election. [I mean] the legal arrangements that are in place and the administrative formalities that we have to go through are sound."

Mr Akufo-Addo called on his supporters to come out in large numbers to vote:

They have to all come out and vote, be part of the process - not just of the voting but the observing of the process. That's what I am expecting our supporters to do."
