7 Types of corruption under Buhari's watch.
1)Inflated government contracts without due process,an example of Maikanti Baru( please note that Buhari is the Minister of Petroleum): On August 30, 2017, the minister of State for Petroleum Resources, Mr. Ibe Kachikwu, revealed in a memo to President Buhari, which ended up getting leaked, that despite the legal requirement for all contracts above $20 million to be approved by the board of the Nigerian National Petroleum Corporation, the Group Managing Director of the NNPC, Maikanti Baru, has unilaterally awarded sundry contracts without due process to the tune of $24.5 billion.
2-Unremmited revenue- THE National Economic Council, NEC, Thursday, directed the federal government revenue agencies like the Nigeria National Petroleum Corporations, NNPC, Nigerian Petroleum Development Companies, NDPC, Nigerian Custom Service, Nigerian Ports Authority among others to refund N526 billion and $21 billion which is about N8 trillion that was under-remitted to federation account.
3) Extortion-Payment of bribe by MTN Amina Oyabola to Buhari's Chief Of Staff -Abba Kyari.
4) Conversion of Public Property To Private Use.Mamman Daura, the man reputed to be the President Buhari right hand man...where he has an office, staff, order meals and has official cars without an official position.
5) Wastefulness- anything you can create to spend money on recklessly. Examples- parking of presidential jet in London City Airport incurring charges of $4000 (N1.44m)a day . N1.2 billion spent on suspended Nigeria Air .
6) Undue influence of fraternity and "my town people"- Buhari surrounded himself with uncle, nephew and "town people"
7) Misuse of security vote -"Anti-corruption group Transparency International said on Monday Nigeria’s government has in the run-up to elections expanded the use of opaque $670 million-a-year funds that fuel graft."
Conclusion the greatest of these is the multi exchange rate by CBN, the poor access the exchange rate at the official rate and the cronies get it for lesser.
I appreciate Dr Datti Ahmed for the intellectual insight into corruption in Nigeria.

Meanwhile the zombies of this regime keep shouting that it's fighting corruption when Buhari himself is corruption personified.
