Dr. Olusegun Mimiko competed in the gubernatorial elections on April 14, 2007, against the incumbent Olusegun Agagu. The Independent Electoral Commission INEC, departing from the norm, announced election results in Abuja, the federal capital, declaring the incumbent the winner. Mimiko contested this decision at the election tribunal and was adjudged winner at the tribunal and the Court of Appeal on February 23, 2009. The Appeal Court, liked the court of first instance, cited massive irregularities in the 2007 election, and ordered that Agagu be replaced by Mimiko as governor. Mimiko then became the first and only member of the Labour Party to win gubernatorial office in Nigeria.
Governor Olusegun Mimiko contested and won re-election on October 20, 2012, for a second term, making him the first governor in Ondo State to win a second term election. Mimiko stood in that election as the Labour Party candidate for Nigeria’s Ondo State and polled the highest votes.
Though his victory was contested by the candidate of the ACN, Rotimi Akeredolu; the candidate of the PDP, Olusola Alexander Oke; and the candidate of the CPC, Olusoji Ehinlanwo, the courts found no grounds to invalidate his election and he was sworn-in for a second term on February 24, 2013. The Ondo State governor, Olusegun Mimiko, on Thursday October 2, 2014 officially decamped to the People's Democratic Party (PDP) from the Labour Party. He and his supporters were received back to the fold by the Vice President, Namadi Sambo Senate President, David Mark; Deputy National Chairman, Uche Secondus; and top party men at the Banquet Hall of the State House, Abuja. His era as governor is recorded as witnessing massive developments in health and education sectors as well in general infrastructure and rural development. His tenure as governor ended on February 24, 2017.
