The Kentucky Rules of Professional Conduct, SCR 3.130, et seq., are mandatory for all Kentucky lawyers. SCR 3.130-3.4(e) provides that a lawyer shall not “assert personal knowledge of facts in issue except when testifying as a witness, or state a personal opinion as to the justness of a cause, the credibility of a witness, the culpability of a civil litigant, or the guilt or innocence of an accused.” SCR 3.130-3.7 generally prohibits a lawyer *733from acting as an advocate at trial where the lawyer is likely to be a necessary witness. The case at bar touches upon the foregoing Rules of Professional Conduct and various rules of evidence. This opinion will examine the propriety of what appears to be a practice common among some lawyers where a witness has made extra-judicial statements to the lawyer pri- or to trial. Thereafter, when the witness fails to give testimony consistent with the prior statements, the lawyer takes such broad liberties in the mode of examination as to essentially give testimony as to the substance of the prior statement.
Appellant Holt was on trial for first degree burglary and complicity to first degree robbery. He appealed to this Court from his convictions and thirty-year sentence. At trial, Holt denied involvement in the crimes. On this appeal, he claims, inter alia, that he suffered prejudicial error by means of improper questioning by the prosecutor of a prosecution witness, Reggie Bell.
Bell was called by the Commonwealth during its case in chief. After establishing that Bell and Appellant had been in jail together, and laying a modest foundation for the intended testimony, the prosecutor, referring to Appellant, asked Bell, “What did he say to you?” Bell answered, “He just said that’s what he was in for.” The prosecutor pressed the witness by asking, “So, he never told you that he did — ,” at which point Appellant’s attorney objected, claiming that the question had been asked and answered. The court overruled the objection and allowed the prosecutor to continue as follows:
Prosecutor: Did he ever tell you that he actually did this robbery at this trailer?
Witness: Nah, he ain’t actually say it was at that trailer. He didn’t actually say that. He just, he didn’t actually just say that he robbed her, but—
Prosecutor: How did he phrase it?
Witness: That they was — ya’ll was trying to put a robbery and a burglary on him.
Prosecutor: Do you remember talking with me this morning?
Witness: Yeah.
Prosecutor: Do you remember telling me that he told you that he did it?
Defense: Objection.
Judge: You can answer.
Witness: Nah, I didn’t actually just tell you that. I didn’t actually just say that he told me that, that he told me that he did it this morning.
Prosecutor: So, you don’t recall ever telling me that the defendant in this case told you that he robbed that trailer?
Witness: Nah, he just told me that’s what they was charging him with.
Prosecutor: But he told you about some dolls?
Witness: He said that was involved with it.
Prosecutor: What did he tell you he did with those dolls?
Witness: Um, in the garage.
Prosecutor: What garage?
Witness: I don’t know whose house, whose it was.
Prosecutor: Do you remember again speaking with me this morning about where the defendant put these things? Witness: Yeah.
Defense: Objection.
Judge: You may answer.
Prosecutor: Do you remember telling me that the defendant told you that it was in his mom’s garage?
Witness: That’s where they found them at, at his mom’s garage or something like that.
*734Prosecutor: But you’re now saying that you don’t recall telling me that the defendant told you that he put them in his mom’s garage?
Witness: Nah, I ain’t never, I ain’t never told you he told me he put them there.
Prosecutor: You’re saying now that you never told me that?
Witness: I never told you that.
Prosecutor: So, he told you that he didn’t do this?
Witness: He never — he didn’t say he did or he didn’t do it. He just said that they had him involved with it.
Prosecutor: Did he tell you anything else about this? He mentioned some dolls, he mentioned a garage. Anything else?
Witness: Nah, he said somebody got hurt in the process, but I don’t know no names or nothing.
From the foregoing, it is clear that despite Bell’s denial of the substance of the statements attributed to Appellant, the prosecutor asserted on at least four occasions that Bell told her that Appellant had admitted the crime. The Commonwealth rested its case without calling any other witness; there was no witness who impeached Bell’s denial of Appellant’s alleged statement. Nevertheless, the prosecutor stated in her closing argument, “I will say this and end it quick. The Commonwealth would never have wasted your time, if it had known what it was going to get out of Mr. Bell. I will move on.”
The effect of the prosecutor’s questions asserting what Bell had said to her placed the prosecutor in the position of making a factual representation. From the tenor of her leading questions to Bell, there is no doubt that she put the very words Bell refused to say in his mouth. The jury was thus informed that Bell had told the prosecutor that Appellant had admitted the robbery. This placed the credibility of the prosecutor before the jury, and from the form of the questions, firmly represented to it that Bell had told her that Appellant had admitted the crime.
More than a century ago in Commonwealth v. Cook,1 this Court considered a circumstance not dissimilar to this one. When the testimony of witness Berry was concluded, but in the presence of the jury, the Commonwealth’s Attorney stated “Because he, Berry, told me and Judge Hor-man, in the witness-room, yesterday, that Owsley never done anything to defendant, and was doing nothing to him when he was shot.”2 The trial court instructed the jury not to consider the statement and reproved the Commonwealth’s Attorney for making it. On appeal, this Court held the remark to be improper and explained as follows:
The conduct of the commonwealth’s attorney was very reprehensible, and he should have been punished by a heavy fine. It is the duty of a commonwealth’s attorney to represent the interest of the commonwealth fully and fairly, with his utmost ability; but it is not his duty to make a statement of fact, the credence of which is always more or less strengthened by his official position, outside of the record or evidence, which may tend in the least degree to prejudice the rights of the accused. The commonwealth desires and is entitled to the conviction of the guilty by fair and honorable means, and upon competent testimony; but it does not desire a conviction by any other means. To accomplish this *735end, it is the duty of the commonwealth’s attorney to devote his entire energy and utmost ability; but, as before said, he is not excusable in making any statement of fact outside of the evidence which may be in the slightest degree prejudicial to the rights of the accused. In this case, the commonwealth’s attorney, not as a witness, made a statement of fact which flatly contradicted the witness Berry, and, if believed, convicted Berry, in the minds of the jury, of perjury. There was a plain course for the commonwealth’^ attorney to pursue, — either to introduce himself or Judge Horman as a witness to contradict Berry; but, not seeing proper to take this course, he should have kept silent as to what occurred in the witness-room, for the reason that a repetition of it, not under oath, in the hearing of the jury, was incompetent evidence, and of a character very damaging to the rights of the appellant, and which doubtless left an unfavorable impression on the minds of the jury, notwithstanding the admonition of the court.
In a case like this, it would better accord with the rights of the accused for the court to suggest to him or to his counsel that if he desired it, and would so request, the jury would be withdrawn and another jury impaneled to try the case. If the suggestion should be declined, the complaint of the accused should not thereafter be heard.3
More recent cases from other jurisdictions have reached a similar conclusion. In Roby v. State4 the prosecutor cross-examined a defense witness about a previous telephone conversation they had about receipts from a restaurant that allegedly were falsely dated in order to provide an alibi for the defendant. As in this case, the prosecutor framed his questions with phrases like, “[ijsn’t it true that you told me,” “did you tell me,” and “[t]he question is whether or not you told me....”5 In so doing, the prosecutor implied that the defendant had previously admitted that he was unsure about whether the date on the receipt was in fact accurate, even though, on the stand, the defendant denied ever being unsure. The Wyoming Supreme Court disapproved of this interrogation technique and determined that the prosecutor was “in a real and not too subtle way presenting unsworn testimony ....”6 The court noted that
[t]his situation can be avoided by following the guidelines set forth in the A.B.A. Standards Relating to the Prosecution Function, § 3.1(f), which provide:
“(f) The prosecutor should avoid interviewing a prospective witness except in the presence of a third person unless the prosecutor is prepared to forego impeachment of a witness by the prosecutor’s own testimony as to what the witness stated in an interview or to seek leave to withdraw from the case in order to present his impeaching testimony.”7
Likewise, in Dean v. State,8 the prosecutor engaged in a similar mode of examination. Specifically, the prosecutor and a witness engaged in the following short exchange:
Q. You remember my telephone conversation with you the other day?
*736A. I was trying to recall it this morning. I can’t recall the specific things that we talked about.
Q. Okay.... Do you recall telling me in our telephone conversation that the defendant would be very likely to do this sort of thing again?9
The defendant objected, and the trial court admonished the jury to disregard the last question. Nonetheless, the Arkansas Supreme Court held that the question was reversible error:
The question by [the] deputy prosecuting attorney ... did not simply seek to elicit testimony from the witness, but, in effect, made a clear statement of fact amounting to testimony by him under the guise of cross-examination. The statement by [the prosecutor], a judicial officer, was made for the sole purpose of convincing the jury that if appellant were allowed to remain free there was expert opinion that he would again commit the crimes for which he was then on trial. This testimony by a court official was a flagrant violation of appellant’s right to a fair and impartial trial as guaranteed by the Arkansas and United States Constitutions and was so clearly prejudicial that the error could not be removed by the trial court’s admonishing statement.10
A leading case directly on this issue is U.S. v. Puco.11 Puco’s co-defendant made a post-arrest, out-of-court statement to an assistant U.S. attorney impheating Puco in drug crimes. The prosecutor called the co-defendant as a witness at trial and asked him about the out-of-court statement. The prosecutor began his questions with phrases such as, “Did you tell me,” or “Do you recall me asking you....”12 The codefendant admitted to making several of the statements, but denied those related to Puco. The court found the questioning to be erroneous:
We find this contention of appellant that prejudicial error was injected here well taken. Using this statement, which was never admitted into evidence against either defendant, in this way in effect placed the credibility of the prosecutor himself before the jury and was therefore highly prejudicial. The prosecutor by his reading from the purported statements and the form of his questions was plainly representing that Gonzalez had in fact made the statements to him. This practice has been widely condemned .... 13
In U.S. v. Shoupe,14 the trial court declared the codefendant a hostile witness, thus allowing the prosecutor to ask him leading questions, but specifically rejected the notion that the witness’s prior statements could be used for impeachment purposes. The prosecutor went on to ask the witness over seventeen questions incorporating the substance of his prior out-of-court statements. The court noted that it could “find no precedent sanctioning the recitation,” and that
[c]ourts have condemned this practice as cloaking potentially self-serving accounts of a witness’s statements with the dignity and credibility of the prosecutor’s office, United States v. Puco, 436 F.2d 761 (2nd Cir.1971), as increasing the probability that the jury will consider the statements as substantive evidence despite any limiting instruction to the con*737trary, Gaines v. United States, 121 U.S.App.D.C. 213, 349 F.2d 190 (1965), as placing before the jury the content of patently inadmissible past recollection recorded, Goings v. United States, 377 F.2d 753, 760 n. 8 (8th Cir.1967), and as bypassing, to the prejudice of the defendant, reasonable alternative measures to accomplish the same legitimate result. United States v. Block, 88 F.2d 618 (2nd Cir.), cert. denied, 301 U.S. 690, 57 S.Ct. 793, 81 L.Ed. 1347 (1937).15
The court held that it was a clear abuse of discretion to allow the prosecutor to incorporate so many such statements, concluding “that the recitation by the prosecutor of the entire substance of a witness’s disavowed, unsworn prior statements, which, if credited by the jury, would be sufficient to sustain a conviction, abridged defendants’ right to a fair trial in violation of the Due Process Clause of the 5th Amendment.”16
Finally, in Berger v. United States,17 the U.S. Supreme Court reviewed various acts of prosecutorial misconduct including the discussion of statements the defendant allegedly made to the prosecutor in the hallway. Commenting on the role of the prosecutor in an adversarial system, the Court said:
The United States Attorney is the representative not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all; and whose interest, therefore, in a criminal prosecution is not that it shall win a case, but that justice shall be done. As such, he is in a peculiar and very definite sense the servant of the law, the twofold aim of which is that guilt shall not escape or innocence suffer. He may prosecute with earnestness and vigor-indeed, he should do so. But, while he may strike hard blows, he is not at liberty to strike foul ones. It is as much his duty to refrain from improper methods calculated to produce a wrongful conviction as it is to use every legitimate means to bring about a just one.18
In light of these broad principles, the Court held that the prosecutor’s misconduct was reversible error:
It is fair to say that the average jury, in a greater or less degree, has confidence that these obligations, which so plainly rest upon the prosecuting attorney, will be faithfully observed. Consequently, improper suggestions, insinuations, and, especially, assertions of personal knowledge are apt to carry much weight against the accused when they should properly carry none.19
The foregoing authorities leave no doubt that assertions of fact from counsel as to the content of prior conversations with witnesses have the effect of making a witness of the lawyer and allowing his or her credibility to be substituted for that of the witness. Such a practice also violates KRE 60320 and KRE 802.21 Any such *738practice is improper and, subject to harmless error review, is an appropriate basis for reversal.
With respect to harmless error, Justice Scott’s dissenting opinion more or less acknowledges error, but contends that it was harmless. As the error implicated federal constitutional rights, a necessary conclusion is that it was “harmless beyond a reasonable doubt.”22
While there was substantial evidence of appellant’s guilt, “[w]e are not concerned here with whether there was sufficient evidence on which the petitioner could have been convicted without the evidence complained of. The question is whether there is a reasonable possibility that the evidence complained of might have contributed to the conviction.”23 When the prosecutor effectively became a witness and confessed guilt for the defendant as if the confession came from his lips, the error was particularly egregious. A confession is devastating evidence of guilt, but, if possible, its effect is elevated when the prosecutor becomes the defendant’s voice. When that happens, the defendant’s bundle of constitutional rights evaporates.
The dissenting opinion forgives the Commonwealth’s Attorney by saying that she was trying to “make the best of a bad situation with a difficult witness.” Hardly a lawyer who has tried a case has not been disappointed by the testimony of a witness on direct examination. Our rules do not provide, however, that when the witness disappoints, the lawyer may testify in his stead. And that’s what happened here.
It will be contended, however, that our view as expressed hereinabove unduly restricts the lawyer’s ability to provide a proper foundation for impeachment of a witness pursuant to KRE 613. KRE 613 provides that “before other evidence can be offered of the witness having made at another time a different statement, he must be inquired of concerning it, with the circumstances of time, place and person present, as correctly as the examining party can present them.”
One of the most common means of witness impeachment is to present evidence that at another time he made a different statement. Our rules require, however, that before evidence of the inconsistent statement may be heard, the witness must be asked about it in the context of attendant circumstances of time, place and persons present. Without such a foundation, evidence of prior inconsistency is not admissible. Therefore, counsel must be permitted the latitude to ask foundation questions for otherwise there will be no ability to impeach the witness by prior inconsistency.
It is possible, however, to establish a proper foundation for impeachment without placing the credibility of the examining attorney in issue. By means of non-leading questions, the witness may be inquired of sufficiently to satisfy the requirements of KRE 613, and upon failure of the witness to testify consistently with his or her prior statement, impeachment testimony from another is authorized. Thus, in the case at bar, counsel could have inquired about the prior conversation and identified the location, persons present, and approximate time. The witness would have been asked if he had made a statement and if so, to repeat that statement. If the witness denied the statement or repeated it in *739a materially different form than the prosecutor recalled, another who was present during the conversation could have testified as to its content, thereby impeaching the witness and placing the statement before the jury. Where, as here, no other party was present, the examining attorney would have no choice but to forego the testimony or abandon her role as an advocate and seek leave of court to testify as a witness.
A significant flaw in this case was failure of the Commonwealth’s Attorney to observe KRE 611(c). The witness was called by the Commonwealth during its case in chief. As a witness for the Commonwealth, leading questions should not have been allowed. If the trial court had sustained an early objection based on the form of the question and directed counsel to refrain from leading questions, counsel would have avoided the temptation to place the substance of the alleged statement before the jury from her lips rather than awaiting the testimony of the witness.
What transpired here is more than some technical violation of evidence rules or proper conduct by lawyers. By means of the prosecutor’s assertions, statements attributed to Appellant were placed before the jury without any witness saying that Appellant made such a statement. This goes to the heart of fundamental fairness and due process of law.
Appellant also complains that the trial court failed to give his tendered instruction on receiving stolen property. Inasmuch as we are reversing for a new trial on other grounds, we deem it unwise to decide this issue in this fact-intensive case. On retrial the evidence may not be the same, and the trial court should determine whether to give a lesser included offense instruction based on the evidence presented. However, we reiterate that it is the duty of the trial court to give instructions covering the whole law of the case, and if there is evidence from which the jury could believe Appellant to have been guilty of a lesser offense rather than the greater offense, a lesser included offense instruction would be given.
As such, we reverse Appellant’s conviction and remand this case for a new trial in conformity with this opinion.
