Osun State Governor Ademola Adeleke was absent during the Peoples Democratic Party governorship primary, where Adedamola Adebayo secured the candidacy for the 2026 election with 919 votes from 957 delegates. A confrontation occurred after the election involving some lawmakers and an Independent National Electoral Commission official, resulting in an assault amidst claims of political interference by Oyo State Governor Seyi Makinde. Despite announcing his resignation from the Peoples Democratic Party, Adeleke's name remained on the ballot. The primary faced confusion due to conflicting directives from factional party officials, leading to a tense atmosphere despite heavy security presence. Adeleke cited a national leadership crisis as his reason for resignation in a letter obtained by the press. The deadline for candidate submission set by the Independent National Electoral Commission is December 15.
