The IPOB leader, while describing the act as evil, promised to shock Nigerians with the revelation on Saturday evening.
In a tweet he shared yesterday, Kanu said he will expose the evil work of a cabal in the presidency.
“The transformation of Jubril Aminu to replace dead Buhari, an evil that will destroy the demonic #Nigeria and free millions of lives,” he tweeted.
“I will expose the dirty work of the Nigerian ruling cabal tomorrow on Radio #Biafra at 6 pm.
“Be ready to embrace the beginning of your freedom.”
