Do you agree with the Senate President?
Senate President Ahmad Lawan said the roof leak that occurred at the National Assembly Complex on Tuesday is proof that the complex is overdue for rehabilitation.
Lawan said Nigerians should have supported the renovation effort because the complex has not been upgraded in over 20 years.
He said the complex is a symbol of democracy that must be protected adding that "If this complex leaks, the interpretation is we're not holding our democracy with the respect it deserves.
