Nigeria's federal government is not speaking with one voice as far as IPOB is concerned.

The Senate President, Bukola Saraki, has faulted the recent proscription of the Indigenous People Of Biafra (IPOB) and the categorisation of the group as a militant terrorist organisation.

Governors from the South East Region have banned the group after it resisted deployment of troops in the region for a military exercise, Egwu Eke II.

The resistance resulted in clashes with the military declaring the group a terrorist organisation.

On Monday, Saraki described the decisions of the governors and the military as unconstitutional.

"Our laws make clear provisions for taking such actions and without the due process being followed, such declaration cannot have effect.

"I am sure the President will do the needful by initiating the right process.

"This will go a long way in demonstrating to the world at large that we are a country that operate by laid down process under every circumstance. So, those who have been hammering on this point should maintain their cool," Saraki said in a post on Facebook.

The Senate President and the leader of the National Assembly also said that the Legislative arm of the government would begin a fact-finding investigation.

He believes it will help determine what actually happened during the period of the military exercise in the South-east.

"We want to be able to sift the facts from the fiction and determine who did what.

"It is quite clear that all the facts are not yet known. We assure Nigerians that there will be no cover up.

"We intend to lay the facts bare," he said.

Dr. Saraki also promised that the National Assembly on resumption would play its constitutional role by addressing all issues agitating the minds of Nigerians.

He also wants leaders of thought -political, religious and traditional - to continue to engage with their subjects on the need to maintain peace.

"I appeal to all our people to always direct their grievances to the right channels," he added.

The Nigerian Armed Forces had deployed troops to the South East Region to check rising insecurity in the region and other vices.

The troops are also to check kidnapping and secession agitation by the IPOB.
