Muhammadu Buhari was on Wednesday re-elected Nigeria's president after a delayed poll that angered voters and raised political temperatures - but the opposition immediately vowed to challenge the "sham" result in court.
It was the second victory at the ballot box for Buhari, a one-time military ruler who in 2015 was elected to lead Africa's most-populous nation and leading oil producer.
"The new administration will intensify its efforts in security, restructuring the economy and fighting corruption," he said.
- 'Up we go!' -
Supporters had gathered outside the party's offices in the capital Abuja late Tuesday as it became clear that Buhari had an unassailable lead, dancing and singing "We're popping champagne!"
