A protest against the handling of the recently finished elections is being led by the presidential candidate of Nigeria's biggest opposition party, the Peoples Democratic Party (PDP), in the nation's capital, Abuja.

Atiku Abubakar and his running mate, Ifeanyi Okowa, are accompanied by their supporters in the demonstration dubbed black uniform protest march.

They claim there was a lack of transparency with the new electronic voter system.

The Independent National Electoral Commission (Inec) has previously denied the complaints.

The ruling APC party's candidate Bola Tinubu was declared winner of the presidential poll with 37% of votes counted. Mr Abubakar finished second with 29%.
