General Secretary of the New Patriotic Party (NPP), Kwadwo Owusu Afriyie has taken on Dr. Charles Wereko Brobby, describing his assessment of Dr Mahamudu Bawumia's performance in the ongoing Presidential Election Petition before the Supreme Court as "sickening". He said it is now evident that Dr. Wereko Brobby’s inexorable frustration in politics is getting the better part of him. Wereko Brobby, obviously not happy with the performance of the petitioners star witness, Dr. Mahamudu Bawumia, in a statement described him as a "clueless witness". Tarzan, as he is affectionately called, has publicly stated his disapproval of the NPP’s decision to challenge the 2012 presidential election in court, and chided the party for making someone who is 'ignorant' about the electoral process its star witness. But in a rebuttal on Asempa FM’s Ekosii Senprogramme Thursday, Kwadwo Owusu Afriyie said Wereko Brobby’s comment is "baseless and illogical". He described Dr. Bawumia as NPP's "darling boy", and for him the party does not need anyone who does not matter in the party to rate his performance in court. Sir John, as he is popularly called, said the former Ghana@50 Secretariat boss is an opportunist who reaped where he did not sow. He alleged that Dr. Wereko-Brobby enjoyed the fruits of other people’s labour in the Kufuor government even though he (Wereko-Brobby) formed his party after losing the NPP primaries ahead of the 2000 elections. He intimated that all the problems NPP is facing now are due to Dr. Wereko Brobby whom he accused of soiling his hands in various deals in the erstwhile Kufuor administration. The NPP scribe said Tarzan has bitten more than he can chew and promised to descend into the gutters with him if he continues being a nuisance to the NPP. He urged Wereko Brobby to remove the spec in his eye before he removes the log in someone’s eye. The NPP man stressed that Tarzan was not a true member of the NPP because no serious party member would object to a collective decision taken by the National Executive Council of the party. Sir John advised Tarzan to direct his energies on removing the skeleton in his cupboard before they come out to haunt him.
