(BBC) – Nigerian President Muhammadu Buhari looks set for re-election, results from Saturday’s general election show.
With results in from most states, he has a lead of more than three million votes over his rival Atiku Abubakar.
Mr Abubakar’s People’s Democratic Party (PDP) has called for a halt in the count, alleging irregularities.
Delays and violence marred the run-up to the vote but no independent observer has said that there was electoral fraud.
Mr Buhari, a member of the governing All Progressives Congress (APC) party, is seeking a second term in office.
So far the APC has 19 states, while the PDP has 16 plus the capital Abuja. The candidate with the most votes is declared the winner as long as they have at least 25% of the votes in 24 or more of the 36 states.
