John Dramani Mahama, the NDC's presidential candidate, has made it clear that he will not debate Dr.

Mahamudu Bawumia, the NPP's candidate.

This comes after President Nana Akufo-Addo challenged Mahama to debate Bawumia on important national issues before the December 7 elections.

Speaking at a rally in Prampram during his campaign in the Greater Accra Region, Mahama defended his time as president and rejected the idea of a debate.
