The President of South Africa Cyril Ramaphosa is presently addressing his Nation at the Parliament: State of the Nation Address (SONA).
It's an open address whereby anybody from any party can ask any questions as regards the Country from the President.

Can Nigeria President try this or adopt this style?

That is how leadership should be. South African president, is already setting good precedence for modern leadership. His ministers and principal officers are in check already few days after his inauguration. But we can't say thesame for our president. Still playing politics with who should be this and that.

Being lackadaisical is now old school, we expect our president to hit the ground running now. Coz you can tell how high a building is going to be by how deep they dig the foundation.
