Defendants are not entitled to rely on a lawyer's advice to testify falsely, and if they do so, there is no sound reason to treat them any differently from defendants who testify falsely entirely on their own initiative. If the allegations of defendant's postconviction petition are true, his complicity with his attorney in presenting false testimony forecloses a claim of ineffective assistance of counsel. People v. Martin, 143 Ill. App. 3d 818, 821 (1986). For the foregoing reasons, the judgment of the circuit court of McHenry County is affirmed.
