Official results show that incumbent Muhammadu Buhari has won Nigeria's presidential election. The opposition has rejected the results, claiming voter fraud and irregularities.
Nigerian President Muhammadu Buhari has secured a second term as the leader of Africa's most populous country, the electoral commission said Wednesday, after a delayed election and opposition claims the vote was rigged.
The former military dictator won by more than 4 million votes, beating his main rival Atiku Abubakar, a former vice president.
Buhari secured 15.1 million votes, while Abubakar of the People's Democratic Party (PDP) received 11.2 million. Voter turnout was a meagre 35.6 percent.
To win, a candidate needed a simple majority of votes nationwide and at least 25 percent support in two-thirds of Nigeria's 36 states and the capital territory.
Supporters of Buhari's All Progressives Congress (APC) celebrated the victory in the capital, Abuja.
Was Nigeria's election fair?
Opposition claims fraud
On Tuesday, the PDP demanded a halt to vote counting from Saturday's election, citing electoral fraud.
Tanimu Turaki, a spokesman for the PDP, said handheld electronic machines that check biometric voter identity cards had been tampered with, leading him to call for an "immediate halt to the ongoing collation of results."
The Economic Community of West African States, the African Union and the United Nations have urged all sides to await official results before filing electoral complaints. It is unclear if Abubakar will challenge the results.
