Peter Obi, the presidential candidate for the Labour Party (LP), has submitted his petition to contest Bola Tinubu's victory in the 25th February election, on behalf of the All Progressives Congress (APC).
At around midnight on Tuesday, Mr. Obi, who finished third in the race, submitted his appeal at the Presidential Election Petition Court in Abuja challenging the results of the vote.
He said that a number of irregularities occurred during the election, including Mr. Tinubu and his running mate Kashim Shettima, not being eligible to run for office.
He also claimed that Mr. Tinubu was unable to win the majority of the legitimate votes cast in the election, just as he was unable to win one-fourth of the legitimate votes cast in Abuja, the Federal Capital Territory (FCT).
Additionally, Mr Obi believes he received the majority of valid votes. The Labour Party candidate asked the court to either declare him the president-elect or declare the election invalid and order a new election.
There are two major prayers and three variant prayers in the petition, for a total of five prayers.
The petition was submitted jointly by Mr. Obi and the Labour Party, his party.
The co-petitioners sued the Independent National Electoral Commission (INEC), Mr Tinubu, Kashim Shettima (vice-president-elect) and their party, the APC, as the respondents.
They submitted their case on Tuesday, beating the 21-day window that started to run on March 1 after INEC announced the election's winner.
