Under the 1999 Constitution of Nigeria, the appointment of ministers and ambassadors must be ratified by the Senate. This means that the President, who has the power to appoint ministers and ambassadors, must submit the names of his nominees to the Senate for confirmation. The Senate then conducts a screening exercise to evaluate the nominees' qualifications and suitability for the positions. If the Senate is satisfied with the nominees' credentials, it will confirm their appointments. However, if the Senate finds any issues or discrepancies in the nominees' records or qualifications, it may reject their appointments. Therefore, the Senate has the constitutional responsibility to ratify the appointments of ministers and ambassadors in Nigeria.
