R.B. BURNS, J.
The defendant was found guilty by a jury of driving while his operator's license was revoked.[1] He raises two questions on appeal.
I.
Was it error for the court to refuse to ask a question pertaining to the state of mind of the veniremen during voir dire examination, when specifically requested to do so by defense counsel?
*584 The court asked whether any additional questions (to the veniremen) were desired, and defense counsel made the following request:
"Ask the jurors whether or not they would give greater weight to the testimony of an officer simply because he is an officer."
Instead of submitting the request in the form of a question to the veniremen, the trial judge instructed the veniremen that they were not to give more weight to the testimony of a police officer merely because he was a police officer.
Defense counsel, in an attempt to ascertain the thoughts of the individual veniremen on the subject, again urged the court to ask the proposed question. The court then stated to the veniremen:
"After I explained it to you I take it you are not to give greater weight to the testimony of an officer simply because they are officers than you would a civilian. Everybody understands that, I take it. You all will follow the law as given to you by the court and you can consider that a preliminary instruction so everybody is willing to follow that. If anybody isn't, why say so right now."
The judge first informed the veniremen that they could not weight a policeman's testimony over that of a non-policeman's testimony, and then asked if anyone was going to ignore his demand. Veniremen who might have been wrestling with their consciences, had the question been properly asked, were not likely to admit noncompliance with the strong judicial mandate.
Defense counsel was effectively precluded from eliciting possible prejudices in favor of police testimony, and such testimony was instrumental in the defendant's conviction.[2]
*585 While a trial judge has wide latitude concerning the scope of juror examination and need not ask the exact question posed by a party,[3] parties are entitled to reveal substantial prejudices which veniremen may possess[4] and have the right to develop a rational basis for the exclusion of prospective jurors.[5]
The manner in which the trial judge phrased defense counsel's question encroached upon these rights and entitles defendant to a new trial.
Since this case is to be retried, we deem it important to discuss the defendant's second issue.
II.
Was it error for the court to deny defendant's motion for mistrial following the prosecutor's mention of defendant's four-page driving record?
While questioning a Michigan public service officer the prosecutor held up a four-page proposed exhibit and then elicited testimony from the officer indicating that the exhibit was defendant's driving record. Although the court instructed the jury to disregard the testimony, by "that time * * * the damage had already been done to defendant's cause in the minds of the jurors". People v. Greenway (1962), 365 Mich 547, 550.
Counsel should not make statements in the presence of the jury in relation to facts which are incompetent to be proved.[6]
*586 This Court continues to have appeals where prosecutors have deliberately attempted to introduce inadmissible evidence and asked objectionable questions for the calculated purpose of prejudicing the defendant's right to a fair trial. The practice must stop.
The trial court erred in not granting defendant's motion for a mistrial.
Reversed and remanded for a new trial.
All concurred.
