Senate President, Bukola Saraki says Nigeria would only attain greatness in unity.
Saraki told newsmen in Ibadan at the weekend that Nigerians, irrespective of political, ethnic and religious affiliations, must shun calls for disintegration.
Saraki, in company with Sen. Abdulfatai Buhari (APC-Oyo North), was in Ibadan for the wedding ceremony of the daughter of APC chieftain, Chief Bisi Akande.
The Senate President was reacting to the ultimatum issued by some northern youths to Igbos to quit the north by Oct. 1 and the counter threats by some other ethnic groups.
Saraki said the unity of the country was not negotiable, adding that Nigerians must come together to achieve peace and progress.
He stated that there was no perfect system, adding the nation only needed improvement from its present state.
