The 2012 flagbearer of the New Patriotic Party (NPP), Nana Addo Dankwa Akufo Addo has responded to a suit brought against him by Justice Kpegah who is accusing him of impersonation.Lawyer and Greater Accra Regional President of the Ghana Bar Association, Frank Davis, entered an appearance on behalf of Nana Akufo-Addo on Thursday.He told Joy News “When a writ is issued and you are served, you have 8 days within which to enter an appearance; so we have entered an appearance.”“Then we have 14 days to either file a defence or bring any consequential process.”Frank further stated that the onus now lies on the former Supreme Court judge to prove his claim of impersonation against Akufo Addo.“We do not need to prove anything, he [Justice Kpegah] should come and let the whole world know why Nana Addo is not a lawyer,” he maintained.Justice Kpegah accused Akufo Addo of impersonating a dead lawyer and again claims the NPP flagbearer was not called to the Ghana bar.
