BBC has revealed that there is no evidence that Nigeria’s president Bola Tinubu forged the Diploma he submitted to the country’s electoral commission.

Allegations that President Tinubu’s certificates were faked went viral on social media following the release by Chicago State University (CSU) of his academic records last week.

We have looked at some of the most widely circulated claims.

The release of the president’s academic documents is the culmination of a judicial case filed in August by one of his main rivals in February’s presidential election, Atiku Abubakar of the Peoples Democratic Party (PDP).

Mr Abubakar was hoping to have the victor disqualified after accusing him of falsifying the CSU diploma of Bachelor of Science in Business Administration awarded in 1979 that he submitted to the electoral authority (Inec).

To obtain evidence for his case in Nigeria, Mr Abubakar approached a US court in August, requesting it to compel CSU to release Mr Tinubu’s academic records through a process called discovery, where the parties exchange information including documents ahead of a trial.

Hence, BBC said there is no evidence that he forged college certificate.
