Enugu State Governor Peter Mbah announced at a press conference in Enugu on 14 October 2025 that he was leaving the PDP to join the All Progressives Congress, describing it as a decision reached after a long period of reflection. The move brought one of the South-East's most prominent PDP governors, along with much of his party structure in the state, into the APC, deepening the ruling party's inroads into a region it has historically struggled to win.
