"It is unfortunate that the enemies within have had a field day in the last few days perpetrating this economic terrorism and do not care about what happens to the image and personality of President Buhari who have been trusted by Nigerians with the mandate to redeem them from sufferings and pains inflicted on us by past leaders of this country". The only understanding after series of meetings and consultations is for fuel to immediately return to the filling stations and let us end this suffering and pains caused by the ineptitude of one man who is abusing his rights and privileges.
