At buharis nod osinbajo signs 2017 budget bill
I think there may be a mistake here.
Muhammadu Buhari is the President of Nigeria, and Yemi Osinbajo is his Vice President. However, it's not possible for Osinbajo to sign a budget bill at Buhari's nod, as the President is the one who signs the budget bill into law.
In Nigeria, the President is responsible for presenting the budget to the National Assembly, and after the budget is passed by the Assembly, it is sent back to the President for signing into law. The President has the power to sign or veto the budget, but in this case, it was President Buhari who signed the 2017 budget bill into law, not Vice President Osinbajo.
So, to clarify, it was President Buhari who signed the 2017 budget bill into law, not Vice President Osinbajo.
