It was gathered that the APC National Chairman resigned to save himself from being removed from office.
A source, who was privy to the details of the resignation, said that Adamu was forced out over many issues, which included his non-support for President Bola Ahmed Tinubu.
According to the source, for the past two weeks, elements within the party have been calling for his resignation, threatening to remove him at the next National Executive Committee (NEC) meeting if he fails to resign.
The source further revealed that the National Security Adviser, Nuhu Ribadu was one of the people who told Adamu to resign because he had become a liability to the party.
He was, however, forced to step down as the party chairman after Imo State Governor and Chairman of the Progressives Governors’ Forum, Hope Uzodinma, told him that if he didn’t resign, they would remove him at the next NEC meeting.
