A new report from the International Monetary Fund (IMF) has projected Nigeria as Africa's biggest economy, in spite of its current challenges.
Nigeria is placed ahead of South Africa and Egypt which are second and third respectively.

In August, Nigeria was reported to have lost its position as Africa's biggest economy to South Africa, following the recalculation of the country's Gross Domestic Product (GDP).But the IMF's World Economic Outlook for October, puts Nigeria's GDP at 415.08 billion dollars, from 493.83 billion dollars in 2015, while South Africa's GDP was put at 280.36 billion dollars, from 314.73 billion dollars in 2015.
