Former President John Dramani Mahama has expressed his warm congratulations to Bola Ahmed Tinubu, who has been sworn in as the new president of Nigeria.

Despite these circumstances, outgoing President Buhari has affirmed the credibility and transparency of the election results.

Former President Mahama took to Facebook to share his message, stating, "Congratulations, my brother, HE Bola Ahmed Tinubu (GCFR), President of the Federal Republic of Nigeria.
