The Supreme Court has dismissed an appeal by the senate president, Bukola Saraki, against his trial for alleged corruption.
Mr. Saraki is facing a 13-count charge of alleged asset declaration fraud.
The Code of Conduct Bureau said Mr. Saraki committed the offence, and maintained a foreign account, when he was governor of Kwara State.
The senate president said the charges were politically motivated, and challenged the powers and composition of the Code of Conduct Tribunal to hear the case.
He also asked the Court of Appeal to quash the charges.
Mr. Saraki later appealed to the Supreme Court after losing at the Court of Appeal.
In its ruling Friday, the Supreme Court affirmed the decision of the Appeal Court.
The highest court dismissed the appeal of Mr. Saraki against the composition of the Code of Conduct Tribunal and the powers of the tribunal, effectively ordering him to stand trial.
