Aрpellant, Javan Foster, was tried and convicted for selling heroin in violation of 26 U.S.C. §§ 4704(a) and 4705(a).

His direct appeal, which was dismissed for lack of prosecution and then reinstated, and his appeal from the denial of his motion to vacate sentence, D.C.,
Appellant Foster and Matthew Harris were tried together on a four count indictment alleging illegal transactions in heroin. The indictment arose from two separate incidents, one occurring on July 7, 1969, and the other on July 18 of that year. Foster alone was convicted for the July 18 sale, while both defendants were acquitted of charges based on the еarlier incident. At trial, Foster and Harris were represented by the same attorney, whom they had retained shortly after their arrest.
An understanding of the issues raised by this appeal requires a brief recapitulation of the testimony presented at trial. The principal government witness, Agent Wheeler, testified that on the dates in question he had approached Harris and offered to purchase heroin. On both occasions, according to Wheeler, Harris spoke briefly with Foster whereupon the latter produced several glassine bags containing the drug, which he handed to Wheeler in exchange for money. The *3 defendants, however, denied selling heroin to Wheeler at any time. As to the July 18 incident, Foster admitted delivering some heroin to Mel Greer, a government informer, but testified that he had done so solely as a favor to one Chris Rodrigues and that he had not retained any -of the proceeds of this sale. Harris’ testimony corroborated Foster’s version of this incident.
Appellant’s motion to vacate sentence was based on the theоry that, due to conflicting interests between himself and Harris, he was denied his sixth amendment right to effective assistance of counsel. We shall turn to that question after a consideration of the issues raised on direct аppeal.
I
Appellant asks us to notice plain error under Fed.R.Crim.P. 52(b) in the trial court’s instructions to the jury on two affirmative defenses. He appears to concede the doubtful applicability of that rule to the present case by suggesting that, because a question of ineffective representation by counsel has been raised, we should relax “the rigorous standards which must be met before we can notice ‘plain error’.” McMillen v. United States,
Appellant first contends that he was entitled to go to the jury on a buyer’s agent defense,
see
United States v. Barcella,
Secondly, appellant contends that he was entitled to an instruction on еntrapment, and that the court’s failure to give such an instruction was plain error despite an apparent waiver by defense counsel. We again need not consider whether this was error notwithstanding the waiver since there was no evidence justifying such an instruction. In Kadis v. United States,
Finally, we find no merit in Foster’s contention that there was insufficient evidence to support his conviction.
II
We now come to appellant’s contention that he was deprived of his constitutional right to effective assistance of counsel because of a conflict of interest with his codеfendant Harris. Both common sense and authority,
see, e. g.,
Glasser v. United States, 315 U.S.

60,
Foster also points to defense counsel’s failure to call certain witnesses and request various instructions as indicative of the inadequate representation which he received. There is no evidence in the record that these omissions resulted from any conflict of interest between Foster and his codefendant.
Ill
Although we hold that the appellant was not adversely affected in this particular case, we are acutely aware оf the dangers to criminal defendants inherent in joint representation. We are also mindful of the difficulties faced by both attorneys and judges in attempting an after-the-fact reconstruction of the prejudice which may have been incurred from such a sharing of counsel. We therefore think it an appropriate exercise of our supervisory powers to promulgate a rule to govern the district courts in criminal prosecutions where one attorney speaks for two or more defendants.
Under those circumstances, where trial commences after the publica *5 tion date of this opinion, it shall be the duty of the trial court, as early in the litigation as practicable, to comment on some of the risks confronted where defendants are jointly represented to insure that defendants are aware of such risks, and to inquire diligently whether they have discussed the risks with their attorney, and whether they understand that they may retain separate counsel, or if qualified, may have such counsel appointed by the court and paid for by the government. For the time being, at least, we leave to the discretion of the trial court the exact time and form of the inquiry. There may be unusual circumstances where, to avoid the possibility of prejudicial disclosures to the prosecution, the court may exercise its discretion to pursue the inquiry with defendants and their counsel on the record but in chambers.
If the court has carried out this duty of inquiry, then to the extent a defendant lаter attempts to attack his conviction on grounds of conflict of interest arising from joint representation he will bear a heavy burden indeed of persuading us that he was, for that reason, deprived of a fair trial.
When a satisfactory inquiry does not appear on the record, the burden of persuasion will shift to the government. If the case comes before us on direct appeal, the government will be required to demonstrate from the record that prejudice to the defendant was improbable. If the issue arises in the context of a § 2255 motion, the government will bear the burden of establishing the unlikelihood of prejudice by a preponderance of the evidence. We are unwilling, at this time, to adopt a rule of automatic reversal and therefore decline to follow the approach of the Court of Aрpeals for the District of Columbia,

Ford v. United States,

Notes
. Both statutes were repealed by Pub.L. 91-513, § 1101(b)(3)(A) October 27, 1970, 84 Stat. 1292, effective date of repeal being May 1, 1971, Pub.L. 91-513, § 1105(a).
. We recognize no distinction between retained and appointed counsel in this regard.
See
Larry Buffalo Chief v. South Dakota,
. While Harris did indeed give testimony placing Foster in the company of Rod-rigues on July 18, Foster himself testified that he met Rodrigues in Harris’ presence and subsequently accepted a package for delivery to Greer. As for the contention that Harris placed Foster at the scene of the July 7 incident, it is simply without foundation in the record.
. For example, Harris’ testimony supported Foster’s claim that he was not present at the July 7 incident.
