The United States, through its State Department spokesman Ned Price, congratulated Tinubu and the people of Nigeria, saying the competitive election represents a new period for Nigerian politics and democracy.

Price acknowledged concerns among some Nigerians over the validity of the results, but called for calm and encouraged political leaders to register their grievances through established legal mechanisms.

“Nigerians are clearly within their rights to have such concerns and should have high expectations for their electoral process,” Price said, adding: “We call on all parties to refrain from violence or inflammatory rhetoric at this critical time.

Similarly, the British Prime Minister Rishi Sunak congratulated Tinubua and expressed willingness to work together to grow security and trade ties between both countries, opening up opportunities for businesses and creating prosperity.

While fielding questions from journalists after the presentation of his Certificate of Return to President Muhammadu Buhari in Daura Katsina on Wednesday, Tinubu acknowledged he had also received a congratulatory message from France President Emmanuel Macron.

In addition, the Economic Community of West African States (ECOWAS) has conveyed its congratulations to Tinubu and appealed to all stakeholders to promote peace and to use constitutional means to address any grievances they may have.

Back at home, some members of the House of Representatives have also congratulated the President-Elect, and charged him to focus on the economy, youth empowerment, education, insecurity, health and agriculture.

Chairman of the Independent National Electoral Commission (INEC) Mahmood Yakubu, declared Tinubu winner of the Presidential Election with 8.8 million votes.

However, a coalition of opposition candidates has rejected the result and called for a cancellation of the exercise, citing irregularities in the conduct of the election. They have also vowed to challenge Tinubu’s victory in the court of law.
