Nigeria's ruling All Progressive Congress (APC) party retained control of the country's commercial hub, Lagos, in state elections marked by low turnout.
Lagos is Africa’s largest city with a population of more than 20 million people.
Voters in the state had last month backed opposition candidate Peter Obi in disputed presidential elections that have been challenged in court.
Incumbent Governor Babajide Sanwo-Olu retained his seat with a tally of over 760,000 votes - double the count of his closest rival - in results announced by the electoral commission.
His opponent rejected the outcome before the final count was announced citing fraud. He vowed to challenge the results.
Nigerian governors control budgets worth millions of dollars and are in charge of schools, hospitals and infrastructure.
