The Presidential Election Petitions Tribunal in Abuja is expected to begin pre-hearing in the petitions challenging the outcome of the February 25 presidential election today.

The candidates of the People's Democratic Party in the election, Atiku Abubakar and that of the Labour Party, Peter Obi are both challenging the outcome of the election where the Independent National Electoral Commission (INC) declared Bola Tinubu of the ruling All Progressives Congress as winner.

Atiku, in his 66-page petition, is praying the tribunal to declare him winner of the poll or order a fresh election.

On his part, Obi, in his petition, is also praying the tribunal to nullify Tinubu’s election.
