This appeal is before us pursuant to G. L. c. 278, §§ 33A-33G. The defendant was convicted on three indictments charging armed robbery and sentenced to serve eighteen to twenty-five years from and after any sentences presently being served. He moved for a new trial on the alternate grounds (a) that the trial judge erred in refusing to allow his trial attorney to withdraw so that he might become an alibi witness for the defense, or (b) that the defendant received ineffective assistance of counsel at his trial. The judge denied the motion after hearing, and the defendant appealed. The Appeals Court affirmed.
Commonwealth
v.
Rondeau,
The South Works Credit Union in Worcester was held up on March 12, 1971, at about 10:40 a.m. by three men. One man, identified, by several witnesses as the defendant, wore a hat, sunglasses, and a false beard that largely obscured his face. This man entered the Credit Union holding a nickel-plated revolver, and he ordered all persons present to stand up and put their hands behind their backs. Two other men, who wore masks, then entered, leaped over the tellers’ counter, and placed about $4,500 in a pillowcase. The gunman told the occupants not to move for a few minutes, and all three individuals then left the premises.
The defendant sought to establish an alibi. One Ronald Grogan was on trial in the Worcester County courthouse on March 12, 1971. He testified that the defendant came to the courthouse that day to offer moral support and that he saw the defendant at various times between 9:30 a.m. and noon. In particular, according to Grogan, the defendant was seated as a spectator in Grogan’s courtroom at 10:00 a.m. and at 11:00 a.m. One Joseph Courtney, who was not a defendant in this case but who was serving a sentence for other unrelated crimes, testified that he was the unmasked, bewhiskered gunman in the Credit Union *410 and that the defendant was not involved. Subsidiary details of Courtney’s story differed, however, from those related by other witnesses. 1 Finally, Detective Oscar Provencher testified to seeing the defendant in the courthouse, but stated that the defendant left the courthouse at about 10:10 a.m.
After the trial the defendant obtained new counsel, who then filed a motion for a new trial. This motion was heard in March of 1976. The defendant and Donald P. Feldman, the trial attorney, testified at the hearing. Mr. Feldman stated that, during the first trial, he was ready to testify under oath to seeing the defendant in the courthouse on the morning in question at fifteen-to-twenty minute intervals. The judge, who was also the trial judge, denied the motion on the basic ground that he disbelieved Mr. Feldman’s account.
The meritorious and dispositive issue before us on this further appeal is whether the defendant was deprived of the effective assistance of counsel by the failure of Mr. Feldman to withdraw from representation and to testify as an alibi witness. 2 No simple constitutional test suffices for resolution of this question. In the absence of firm guidance by the Supreme Court, the Courts of Appeals have fashioned divergent standards against which to
*411
measure the effectiveness of criminal trial attorneys.

In addition to a showing of incompetence of counsel, our cases usually require a demonstration of prejudice resulting therefrom.
Commonwealth
v.
Bolduc,
Within the analytical framework we have summarized, the motion for a new trial presented a close question to the trial judge. On the one hand, Mr. Feldman cogently presented an alibi defense and attempted to impeach the identification testimony of prosecution witnesses. Ineffectiveness is not established simply by showing that Mr. Feldman failed to call an additional witness (himself) to bolster the defense case.

Notwithstanding our conclusion that, in view of the judge’s findings, there was no error, we inquire further whether there was a "a substantial risk of a miscarriage of justice”

We think that the ethical infraction committed by Mr. Feldman was sufficiently below the required standard of professional conduct as to justify a new trial. See

The conflict of interest present in this case was, to be sure, exceedingly subtle. That very subtlety emphasizes the difficulty faced by a convicted defendant in showing actual prejudice. See

v.
Geraway,
We hold that the defendant was denied the effective assistance of counsel by reason of the failure of the attor
*417
ney to withdraw when the need for his testimony became apparent. We believe that trial judges should take early and effective action to prevent similar problems from arising. "We deem [DR 5-101(B), 5-102(A)] to require that the court first consider whether the attorney’s testimony will be necessary to protect his client’s interests and, if it concludes such testimony will likely be necessary, that it order a timely withdrawal consistent with minimizing prejudices which may result from the substitution of counsel.”
Comden
v.
Superior Court,
For the reasons stated, the judgments of the Superior Court on the three indictments are reversed, the verdicts set aside, and the case is remanded to the Superior Court for a new trial.
So ordered.
Notes
Two tellers, the manager, and a customer of the Credit Union testified for the Commonwealth. Three stated that the gunman wore amber sunglasses, whereas Courtney said he was wearing blue sunglasses. One teller said the pillowcase was blue, whereas Courtney said it was white. Courtney contradicted testimony that the gunman wore a blue jacket and backed out of the building. Finally, Courtney testified to seeing a puddle on the floor beneath one of the tellers that no other witness described. The defendant did not recall these witnesses for corroboration or identification.
The trial judge found as a fact that Mr. Feldman had not attempted to withdraw, and the record contáins no evidence to the contrary. To the extent that the motion for a new trial was based on the contention that the judge erred in refusing to allow Mr. Feldman to withdraw, therefore, the Appeals Court correctly affirmed the denial thereof. See Commonwealth v. Brown, ante 165, 171 (1979), and cases cited.
The Second and Tenth Circuit Courts continue to insist that “to be of constitutional dimensions the representation [must] be so woefully inadequate as to shock the conscience of the Court and make the proceedings a farce and a mockery of justice.”

Commissioner, Dep’t of Corrections,
The other Circuit Courts have adopted more lenient standards that, while appearing tautological, tend to equate with the tort concept of professional competence. See
United States
v.
Bosch,
The rules cited in the text provide as follows:
"DR 5-102 Withdrawal as Counsel When the Lawyer Becomes a Witness.
"(A) If, after undertaking employment in contemplated or pending litigation, a lawyer learns or it is obvious that he or a lawyer in his firm ought to be called as a witness on behalf of his client, he shall withdraw from the conduct of the trial and his firm, if any, shall not continue representation in the trial, except that he may continue the representation and he or a lawyer in his firm may testify in the circumstances enumerated in DR 5-101(B)(l) through (4).”
DR 5-101(B) in turn provides:
"(B) A lawyer shall not accept employment in contemplated or pending litigation if he knows or it is obvious that he or a lawyer in his firm ought to be called as a witness, except that he may undertake the employment and he or a lawyer in his firm may testify:
(1) If the testimony will relate solely to an uncontested matter.
(2) If the testimony will relate solely to a matter of formality and there is no reason to believe that substantial evidence will be offered in opposition to the testimony.
(3) If the testimony will relate solely to the nature and value of legal services rendered in the case by the lawyer or his firm to the client.
(4) As to any matter, if refusal would work a substantial hardship on the client because of the distinctive value of the lawyer or his firm as counsel in the particular case.”
Rule 12 of the Superior Court (1974) provides:
"No attorney shall be permitted to take part in the conduct of a trial in which he has been or intends to be a witness for his client, except by special leave of the court.”
Objective rules of attorney conduct, like those cited, may provide appropriate evidence of what constitutes normally competent representation. See
Pires
v.

Commonwealth
v.
Wright,
The record abounds with situations where Mr. Feldman argued with witnesses and to the jury concerning the content or meaning of conversations to which Mr. Feldman was a party. These situations exemplify the danger sought to be avoided by (EC) 5-9. We do not, however, rest our decision on the largely conjectural impact of these incidents on the jury. Rather, we are concerned with the dilemma created by Mr. Feldman’s failure to withdraw as counsel for the defendant.
One commentator has argued that the concern of the ethical rule under consideration "is not protection of the client’s interests but the integrity of the attorney’s professional role and the preservation of its uniqueness.” Enker, The Rationale of the Rule that Forbids a Lawyer To Be Advocate and Witness in the Same Case, 1977 Am. B.F. Res. J. 455, 464. This view implies that the remedy of new trial is not required when an attorney continues to represent a criminal defendant. We disagree. The conflict engendered in the attorney’s own mind may have unmeasurable adverse effects on the client’s interests. It is the conflict alone which renders assistance ineffective.
