Flagbearer of the National Democratic Congress (NDC) John Dramani Mahama has accused his counterpart in the New Patriotic Party (NPP) Vice President Dr Mahamudu Bawumia of lying during the media encounter held by the latter on Sunday, August 25 just a day after the NDC launched its manifesto. In the view of Mr Mahama, Dr Bawumia was exposed during the media encounter because of the 'sudden stammering posture" he adopted. Mr Mahama further accused Dr Bawumia and the NPP of using the media encounter to divert the attention of Ghanaians from the NDC manifesto. Speaking during day one of his 2-day in Ada as part of his Greater Accra Regional campaign on Tuesday, August 27 he said "Just yesterday the Cedi crossed the 16 Cedi to one dollar barrier. When you do something with a devious intention it backfires on you, we announced we were going to launch our manifesto on the 24th  of August, immediately our opponents announced that they were going to do a media encounter on the 25th of August, the very next day. "The intention for doing that media encounter the next day after we had announced our manifesto was to get the attention of Ghanaians from the NDC manifesto, that was the main reason that they decided to do a media encounter the very next day after we launched our manifesto. "When you do something with devious intentions, it backfires on you.
