Provocation in a corruption case and admissibility of evidence

I've read that in corruption cases, the defense often focuses on possible provocation of a crime by law enforcement. If, for example, I become a suspect in corruption and claim that I was provoked by law enforcement officers, can the court still use the evidence obtained during such an operation against me? What conditions must be met for such evidence to be inadmissible, and what role does the recording of the search process play?
