The President, Major General Muhammadu Buhari (retd.), on Thursday, wondered why some Igbo men are clamouring for separation.
He described as “unthinkable” attempts by any Igbo man to leave the country.
The president said Igbo people are relevant in Nigeria, adding that they have successful businesses across the country.
The President spoke at a town hall meeting with South-East leaders during his one-day official visit to Imo State.
