 Social Economic Rights and Accountability Project has asked President Mohammad Buhari to investigate how over 11 trillion Naira, meant to provide regular electricity supply, has been allegedly squandered by government since 1999. Sareb made the request in a letter signed by his deputy director, Kola Waliolua Dari, on Sunday. The letter followed the collapse of the national greed, which has plunged the country into total darkness. Sareb urged the president, urgently to implement document report of cases of corruption in electricity sector and ensure full accountability and restitution. Sareb said the failure of successive government and high ranking government officials to prevent corruption in the electricity sector and to bring suspected perpetrators to justice is the primary cause of the persistent crisis in the sector, including the exploitation of electricity consumer and collapse of the electricity greed.
