Vice President Kashim Shettima has arrived at the Presidential Election Petition Tribunal.
Shettima, representing President Bola Ahmed Tinubu, has reportedly taken his seat at the spot allocated to him.
Tinubu is currently in India at the G-20 leaders summit. He arrived New Delhi on Tuesday and had reportedly already begun wooing Indian investors at the summit.
The tribunal is set to rule on the Petition challenging the declaration of Bola Tinubu as the winner of the February 25 presidential election.
The Independent National Electoral Commission had on March 2 declared Tinubu of the All Progressives Congress as the winner after the polls.
However, the result was challenged in court by Peter Obi of the Labour Party, Atiku Abubakar of the Peoples Democratic Party and the Allied Peoples Movement.
