"Indeed he’s made a lot of contentious statements that I would have wished that you had him here, so that we would debate those issues, but essentially our parties are involved in agreeing the format of the debate, who organises it and all that, and, so, it’s not for me to say.

"I’m sure that the NDC party at the appropriate time, if they are invited to debate, will have to take a decision on whether they feel comfortable with whoever is organising the debate and all that...but, like I said, I’m willing, even this afternoon, if Nana presented himself, to take him on all those contentious statements that he’s made," the president said on Accra-based TV3.
