El-Rufai, who is a founding member of the ruling party, announced that he has joined the Social Democratic Party, SDP, on Monday.
He cited the unhealthy situation within the APC as the reason he decamped.
The immediate past Kaduna State governor, Nasir El-Rufai, has revealed he met with former President Muhammadu Buhari before he left the All Progressives Congress, APC.
Speaking in an interview with BBC Hausa Service on Wednesday, El-Rufai spoke about consulting various political figures before his decision.
One of such people was Buhari, who ruled Nigeria until 2023.
El-Rufai said, “I left the APC with his full knowledge.
“My first godfather is Muhammadu Buhari. For the rest, I will not mention them because if I do, they’ll be pressured.”
