He said they are both concerned about unity and security in the country.
“We discussed the way forward for the country and this country is important and greater than anyone’s personal ambition,” Kalu said.
“We have been together and concerned about the stability, progress, development and security of the country.
“The future of our youth is more critically important than selfish and personal intentions.”
