Nigerian President Muhammadu Buhari has been re-elected for a second four-year term, results from Saturday’s general election show.
The 76-year-old defeated his main rival, former Vice President Atiku Abubakar, with a margin of just under four million votes.
Mr Abubakar’s People’s Democratic Party has rejected the result.
Delays and violence marred the run-up to the poll but no independent observer has cited electoral fraud.
Final results released by the Nigerian electoral commission (Inec) show Mr Buhari was re-elected with a margin of just under four million votes.
The commission will make a formal declaration on Wednesday.
Turnout was just below 35% of registered voters.
