A former General Secretary of the New Patriotic Party,
Sir John, as he is popularly known made this statement after President John Mahama told the BBC that he has never taken a bribe.
In his response to the President's assertion on Adom Fm on Friday (May 13), said the facial expression of the President while answering the question showed he was not being truthful.
Owusu Afriyie also said the President's claim should be doubted citing SADA, GYEEDA, Waterville, STX Housing deal, Smarttys and other corruption scandals under the NDC's eight years in office.
He alleged the president's failure in prosecuting ministers and officials in his administration who were involved in the famous corruption scandals suggests that he benefitted from the deals.
Owusu-Afriyie, who is also a private legal practitioner claimed he was aware of various deals that have been covered up by the Mahama administration.
