African Democratic Congress

The African Democratic Congress (ADC) is a political party in Nigeria. The first National Chairman of the party was Ralph Nwosu. He was the National Chairman until 2025, when he stepped down for former Senate President David Mark during coalition talks. The party has one member in the House of Representatives, Leke Abejide, currently representing Yagba East/Yagba West/Mopa Moro Federal Constituency of Kogi State. There are no ADC senators in the Nigerian Senate.

In 2025, former Vice President Atiku Abubakar left the Peoples Democratic Party to join the ADC as part of a coalition to challenge the APC in the 2027 election. Peter Obi, former Labour Party presidential candidate, joined the coalition but has not formally registered with the ADC.

ADC leaders described the move as an attempt to prevent one-party rule by the All Progressives Congress, and to present a united front in the 2027 presidential elections. Analyst Iliyasu Hadi suggested that this realignment would lead to the ADC emerging as Nigeria's main opposition party.
