After 25 days President Buhari lost one of his most trusted Chief of Staff, Abba Kyari to death, he has Tuesday appointed Professor Ibrahim Gambari as the new Chief of Staff.
Professor Ibrahim Gambari was the least person many Nigerians ever thought as a replacement for Abbah Kyari, as he is neither a politician nor live in the corridors of power.
However, there are many things you need to know about him and his intimidation credentials.

He attended King’s College, Lagos for his secondary education and subsequently attended the London School of Economics where he obtained his Bachelor’s degree in Economics with specialisation in International Relations.

Mr Gambari was a research fellow at the Brookings Institution also in Washington D.C. and a Resident Scholar at the Bellagio Study and Conference Center, the Rockefeller Foundation-run centre in Italy.
Away from his strides in the academics, Mr Gambari was a renowned diplomat who has represented Nigeria in several international interfaces.
He served as the Minister for External Affairs between 1984 and 1985 when Mr Buhari was the military Head of state.
He was the Chairman of the UN Special Committee Against Apartheid between 1990 and 1994, during which he worked closely with African governments to coordinate UN policy to eradicate apartheid, thereby building trust and confidence with governments and policymakers in member countries of the Southern African Development Community (SADC).
