This study examines the role of party congress in Nigeria as the cornerstone of democratic governance. Through the utilization of Key Informant Interviews (KIIs) and extensive literature review, the study explores the significance of party congress in shaping democratic process within the Nigerian political landscape. Key Informants including ward party chairmen, women, youth leaders and party chieftains were interviewed to gain insights into the functions and impact of party congress on democratic governance in Nigeria. The findings highlight the role of party congress as a platform for party members to participate in decisionmaking process and candidate selection. The study unveils a concerning trend where party elites frequently manipulate and dominate the conduct of party congresses, leading to the imposition of preferred candidates for general elections. This practice undermines the democratic principles of inclusivity, transparency, and fair competition within political parties, ultimately weakening the democratic governance system in Nigeria. The study recommends the need for reforms and the involvement of civil society organizations to put pressure on political parties to embrace and adhere to the electoral act and political parties’ guidelines for conduct of open and transparent party congress system. This will guarantee credible party congress and enhance democratic governance in Nigeria.
