The Minister of State for Petroleum, Ibe Kachikwu, has reported the Group Managing Director of the NNPC, Maikanti Baru, to President Muhammadu Buhari, urging him to take urgent actions on matters ranging from alleged illegal practices to insubordination. Mr. Kachikwu said he found it pertinent to call the attention of the president to his misgivings because they’re capable of hindering progress in the country’s petroleum sector or even reverse recorded strides. Mr. Kachikwu said he wrote the August 30 letter to Mr. Buhari after concerted efforts to have a one-on-one appointment with the president at the State House fell through. The letter, which emerged on the Internet Tuesday, was widely circulated on Twitter. It is not immediately clear how it made it to the public domain. The minister said he suffered “disrespectful and humiliating conducts” from Mr. Baru.
