The Peoples Democratic Party (PDP) has come down heavily on former Information Minister, Mr. Labaran Maku de­scribing him as a destroyer and an ungrateful party man.

North Central Zone Vice Chair­man of the PDP Alhaji Yussuf Ayitogu who gave the thumbs down in Minna also disclosed that Maku was out to destroy the PDP in Nassarawa State by his defection to the All Progressive Grand Alliance (APGA) after he lost out in the party gubernato­rial primary election in the state.

Even without being told a practice like this is every where, when you're in affair of leadership or rich many people would pretend to love you, if they have their way they would bring you down and claim isn't the fault if caught.
So nothing new here.
