President Muhammadu Buhari met behind closed doors with former President Goodluck Jonathan, in his office at the Presidential Villa, Abuja.
The agenda of the meeting was unknown to newsmen, while no official statement has been issued on the outcome of the meeting.
Jonathan, who is ECOWAS Special Envoy to the Republic of Mali, had been updating President Buhari on efforts by West African leaders to restore stability to the country.
President Buhari recently came back from New York, where he attended the 76th Session of the United Nations General Assembly UNGA, with a special request from the UN Secretary General, Antonio Guterres, to help in restoring socio-political order in troubled West African countries.
Guterres had commended Buhari for his leadership roles in Africa as well as stabilisation of the West African sub-region.
