He made the call on Friday at the 3rd Adada Lecture organised by Association of Nsukka Professors, Nsukka, Enugu State.
The theme of the lecture was “Restructuring and the Nigeria Youth.”
He said countries in South America used single tenure to stabilise their democracy, adding that one of such countries, Mexico, was still practicing single term.
“Single presidency tenure of six years that rotates among the six geo-political regions will promote unity and loyalty to the nation.”
Stressing the need to restructure the county, Ekweremadu said it would not divide the country as feared by some people, while noting that it would rather, strengthen and re-position the nation.
He identified ethnic and religious sentiment, ignorance and fear of the unknown as some of the challenges facing restructuring.
He said restructing would enable regions to harness their resources outside oil, “especially given that the black gold was undergoing shocks in the global oil market.
“The market for crude oil is reducing by the day as countries like Britain and France now have laws that will ban the use of diesel and petrol cars by 2030.
“Also, many countries have started using electric cars.
“Restructuring is the only way to restore the lost glory of the country as it would enable states to have enough resources to fund education, security and give basic amenities to their people.
“Restructure with devolution of power at the centre would reduce political tension as well as make the centre unattractive,” he said.
Ekweremadu urged youths in the country to close ranks and support restructuring as it would create employment and guarantee better future.
