Buhari appointed new chairman for nrc

I think you may be referring to the recent appointment of a new Chairman for the Nigerian Broadcasting Corporation (NBC), not the National Research Council (NRC).

On August 24, 2021, President Muhammadu Buhari appointed Balarabe Shehu Ilelah as the new Chairman of the National Broadcasting Corporation (NBC). Ilelah, a veteran journalist, takes over from Professor Armstrong Idachaba, who was acting chairman of the corporation.

The NBC is a regulatory body responsible for overseeing the broadcasting industry in Nigeria, ensuring that broadcast stations comply with the country's broadcasting laws and regulations.

Please note that the National Research Council (NRC) is a different entity, and I couldn't find any information on a new chairman being appointed for that organization. If you have any further questions or clarification, feel free to ask!
