Nigeria’s presidential election tribunal ruled on Wednesday that Nigeria’s main opposition parties failed to prove claims of electoral malpractice against the governing All Progressives Congress (APC) in February’s disputed elections.

“This petition is hereby declared unmeritorious,” one of the judges said, as the tribunal rejected the opposition challenge to Bola Ahmed Tinubu’s win in the presidential election.

The challenges came after one of the country’s most tightly fought elections, in which former Lagos governor Tinubu won 37 percent of the vote, beating Atiku Abubakar of the People’s Democratic Party (PDP) and Peter Obi of the Labour Party to secure the presidency of Africa’s most populous nation.

Abubakar and Obi had asked the court to invalidate the election, alleging irregularities.

Judges rejected all claims made by Labour Party candidate Obi, including fraud, charges electoral authorities broke the law and allegations Tinubu was ineligible to run.

The court was also reading its judgement on a second opposition party petition, which is also expected to be dismissed. Filed by PDP candidate Abubakar, it lays out similar complaints against the February 25 election results.
