Adams Aliyu Oshiomhole (born 4 April 1952), is a Nigerian politician and the former national chairman of the All Progressive Congress. He had previously served as the president of Nigeria Labour Congress from 1999 to 2007 and the executive governor of Edo State, Nigeria from 2008 to 2016.
As APC national chairman, he was suspended from office by the Abuja Court of Appeal on 16 June 2020.
In April 2007, Adams Oshiomhole ran for Governor of Edo State under the Action Congress Party, with which his Labour Party had entered a strategic alliance. Oserheimen Osunbor of the People’s Democratic Party (PDP) was declared the winner. However, the AC contested the election on the basis of various irregularities. On 20 March 2008, an Edo State election tribunal nullified the election of Oserheimen Osunbor and declared Oshiomhole the winner. On 11 November 2008, a federal Appeal Court sitting in Benin City upheld the ruling of the state’s elections petitions tribunal, declaring Oshiomole to be the Governor of Edo State. The decision was based on several voting irregularities.
In 2012, he was elected to a second term, winning the elections in a massive landslide. He ended his tenure on 12 November 2016.
On 23 June 2018, Adams Oshiomhole emerged as the national chairman of the All Progressives Congress (APC) in Nigeria following a voice vote by delegates at the party National convention.
