He said anybody who attempted to deter his administration from fighting corruption would suffer the consequences.
Buhari, who spoke in English and Hausa languages handed down the warning during the breaking of Ramadan fast, Iftar, he organised for some categories of people inside the Presidential Villa, Abuja.
The President regretted that the elite were self-centred and were only thinking about themselves.
“Whoever deter us from fighting corruption will suffer the consequences. It is unfortunate that the elite are self-centred and they only think about themselves.
“Be assured that we care about you at all times. This government is concerned about your welfare and we will work hard to improve it,” Buhari told his guests that included the physically challenged, the Internally Displaced Persons, taxi drivers, commercial motorcycle riders, artisans such as butchers, hairdressers, barbers, tailors, members of the Buhari Support Organisation, President’s neighbours in Lobito Crescent, and junior workers in the headquarters of the All Progressives Congress.

An IDP, Musbau Diti, who spoke on behalf of others, urged the President to do more to alleviate the sufferings of people in the different IDP camps across the country.
He also urged Buhari to set up a commission for persons with disabilities.
