The BBC maps the challenges facing Nigeria, Africa’s most-populous nation and largest economy, as it approaches a presidential election 20 years since the return of democracy:
Four years ago, President Muhammadu Buhari’s All Progressives Congress (APC) dominated the north and south-west of the country whereas the party’s main rival, the People’s Democratic Party (PDP), was more popular in the south and south-east.
However, unlike in the 2015 election, when a northerner, Mr Buhari, faced a southerner, incumbent President Goodluck Jonathan, this time the main challenger is the PDP’s Atiku Abubakar, who is also from the north.
Analysts say the election is too difficult to call and the result is likely to be close.
The APC could suffer in the country’s Middle Belt, Benue and Nasarawa states, as there is dissatisfaction with the failure to deal with communal violence there, the BBC’s Abuja editor Aliyu Tanko says.
The APC is popular in the two states with the largest number of voters – Lagos and Kano – but there is the danger of voter apathy and a low turnout could become a problem.
