The defendant, William Tosté, was found guilty of murder, in violation of General Statutes § 53a-54a, by a jury of twelve. In this appeal, the defendant pursues five claims of error, only two of which are discussed in this opinion.
Thе defendant assigns as error the court’s admission of testimony by a psychologist and a psychiatrist, each of whom examined the defendant. Since each of these experts testified in a differеnt capacity, we review their testimony separately.
Marvin F. Mankowitz, Ed. D., licensed as a consulting psychologist, examined the defendant pursu
*628
ant to a defense motion but was called to testify as a state’s witness. The defendant contends that the admission of Mankowitz’ testimony violated the attorney-client privilege and, thus, the defendant’s sixth amendment right to the assistance of counsel. Where a psychiatric expert, whether psychiatrist or psychologist, is retained by a criminal defendant or by his counsel for the sole purpose of aiding the accused and his counsel in the preрaration of his defense, the attorney-client privilege bars the state from calling the expert as a witness. The fact that the psychiatric expert was appointed by the court rather than employed by the defense is irrelevant; the law affords no lesser protection for a defendant who is indigent than for one with means to retain his own psychiatrist to prepare a defense. This rule is consistent with a majority of jurisdictions who have resolved this issue.
United States
v.
Alvarez,
*629 The state also called Robert Miller, M.D., a psychiatrist, to testify to the defendant’s mental state. The defendant claims that the court’s admission of his testimony was error because the defendant’s communications with Miller were protected by the psychiatrist-рatient privilege as provided in General Statutes §§ 52-146d-52-146j. Although Miller was engaged by the state to examine the defendant for the state, the record does not support the state’s claim that his services were a result of a court order as required by § 52-146f.

White,
In his next assignment of error, the defendant contends that the court improperly included the
M’Naghten
and
Durham
rules and omitted the “irresistible impulse” rule in its charge to the jury on the defendant’s insanity defense.
M’Naghten’s Case,

Durham
v.
United States,
Until 1967, Connecticut’s common-law test of insanity as a defense to a crime prоvided: “(1) that an accused, to be the subject of punishment, must have had mind, capacity, reason and understanding sufficient to have enabled him to judge of the nature, character and consequеnces of the act charged against him, that the act was wrong and criminal, and that the commission of it would justly and properly expose him to punishment; and (2) that, in committing the act, he was not overсome by an irresistible impulse arising from mental disease.
State
v.
Davies,
In 1967, the General Assembly adopted the model penal code dеfinition of insanity; General Statutes § 54-82a, now § 53a-13; 4 as a statutory standard to be invoked in lieu of the common-law test. The American Law Institute drafters of this provision believed that “the M’Naghten rule is right as far as its princiрle extends .... [But t]he question is whether the rule goes far enough to draw a fair and workable discrimination. Almost all informed opinion holds that it does not . . . .” Wechsler, “Codification of Criminal Law in the United States: The Model Penal Code,” 68 Colum. L. Rev. 1425, 1442 (1968). The drafters concluded that “no test is workable that calls for the complete impairment of ability to know or to control . . . ;” Wechsler, op. cit. 1443; and drafted the “substantial capacity” test adopted by the Connecticut legislature in 1967.
In its charge to the jury, the trial court properly instructed the jury with the statutory language three times. Between the first and secоnd repeti
*632
tions of the statute, however, the trial court charged the
Durham
rule in substance;

between the second and third repetitions, it recited the
M’Naghten
rule.

The defendant contends that the only standard by which the defendant’s insanity should have been evaluated was that found in General Statutes § 53a-13. The
Durham
rule was explicitly rejected by this court in
State
v.
Davies,
It might be argued that since the M’Naghten rule is a more stringent test, even though there was error in submitting the rule to the jury, the charge was favorable to the defendant and, hence, harmless. The reference, in substanсe, to the elements in the Durham rule, which was in error, and the commingling of the old common-law rules with the statutory rule, could only create confusion as to what was the correct standard for determining *633 insаnity. Moreover, the supplemental charge did not clear up this confusion.
The defendant also claims that the court erred when it denied his request to charge on irresistible impulse. The defendаnt contends that the statutory definition of insanity found in § 53a-13 did not replace this charge at common law: If, in committing the act, the accused was overcome by an irresistible impulse arising from mental disease, then he may be found not guilty by reason of insanity.
State
v.
Conte,
In sum, the only standard by which to determine insanity as a defense to a crime is that found in General Statutes § 53a-13. Those portions of the trial court’s instructions to the jury which included previously accepted common-law definitions and the principles, of the Durham, rule, previously rejected by this court, were harmful error.
The other assignments of error are not of sufficient consequence to require discussion. There is harmful error in none of them.
There is error, the judgment is set aside and a new trial is ordered.
In this opinion the other judges concurred.

The minority position is enunciated in
People
v.
Edney,
The attorney-client privilege does not protect communications between the defendant and a psychiatrist appointed by the court to prepare a report for the court, because such communicatiоns are not made to the defendant’s attorney at his request for purposes protected by the attorney-client relationship.
In
State
v.
White,
“[General Statutes] Sec. 53a-13. insanity as defense. In any prosecution for an offense, it shall be a defense that the defendant, at the time of the proscribed eonduet, as a result of mental disease or defect lacked substantial capacity either to appreciate the wrongfulness of his conduсt or to conform his conduct to the requirements of law. As used in this section, the terms mental disease or defect do not include an abnormality manifested only by repeated criminal or otherwise anti-social eonduet.”
The trial court instructed the jury that: “For a person not to be responsible for his criminal conduct there must be a causal relation between the mental disease or defect that he has at the time of that conduct, if any is found in the criminal conduct, so that it can be found that were it not for the mental disease or defect that conduct would not have takеn place.”
The trial court instructed the jury that: “The definition of insanity would include a mind which is either so naturally weak or so impaired by disease' or otherwise as to make its possessor incapable of distinguishing right from wrong.”
