Tinubu, represented by his Vice-President, Senator Kashim Shettima, made this call while delivering his address at the general debate of the 80th session of the United Nations General Assembly in New York City.
"It is necessary for Nigeria to have a permanent seat on the Security Council. This is an important part of the reforms to restore credibility to this institution, which is the cornerstone of the global cooperation system," he said.
The President said the United Nations would only regain its prestige if it aligns with the current global reality, rather than being constrained by its past.
He explained that when the United Nations was founded, Nigeria was a colony of 20 million people, without a voice at the table deciding its future.
"Now, however, we are a free nation of over 236 million people, and projected to become the third most populous country in the world in the coming years. Nigeria has long been a pillar of security in the African continent, and a reliable partner in global peacekeeping operations," said Tinubu.
He stated that Nigerian troops have participated in 51 out of 60 peacekeeping missions conducted by the United Nations since gaining independence in 1960.
The President also said the country has not stood alone in the fight against terrorism, having worked with neighboring African countries through the Multinational Joint Task Force (MNJTF).
Tinubu said, "Nigeria has learned lessons from its long struggle against extremist groups." He also said, "The reason Nigeria speaks on the Gaza conflict, the attack on Qatar, and other regional tensions is because of the experience the country has gained from such endless conflicts that have no clear beginning."
The President added that "Nigeria supports the UN Secretary-General's UN80 Initiative, which calls for reforming the organization's structure to make it fit for purpose, and to end duplication and waste of resources."
