The court properly denied defendant's motion to withdraw his guilty plea, since the record establishes that the plea was knowing, intelligent and voluntary ( see, People v. Fiumefreddo, 82 N.Y.2d 536, 543), and since defendant failed to support his claim of coercion or judicial bias with anything other than conclusory allegations ( see, People v. Frederick, 45 N.Y.2d 520).
