The defendant has appealed from his conviction of five counts of larceny in the first degree, in violation of General Statutes § 53a-122, and one count of larceny in the second degree, in violation of General Statutes § 53a-123, 1 based upon his conversion of tax monies collected on behalf of the city of Waterbury. These charges of larceny against the defendant arose from incidents which occurred during his tenure as a deputy sheriff of New Haven County. At trial the state presented the testimony of numerous witnesses, the substance of which was that the defendant collected back taxes owed the city of Waterbury, deposited the money in a bank account and issued checks on that account for his personal use. The defendant testified on his own behalf and called several witnesses, three of whom testified only to his good character.
*561 The defendant claims a new trial on the ground that the trial court erred in failing to grant either of his two motions for a mistrial. According to the defendant, his motion for a mistrial should have been granted when: (1) during his cross-examination, the prosecutor implied by a question that the defendant had used city funds to pay a gambling debt; and (2) during closing argument, the prosecutor urged the jury to draw an unfavorable inference from the defendant’s failure to call a witness whose testimony had been excluded from consideration of the jury by the trial court. We find error only in the refusal to declare a mistrial on the basis of the comments made by the prosecutor during closing argument.
I
The defendant’s first claim of error involves the proper bounds of cross-examination. During its case in chief the state introduced financial records showing disbursements made from the bank account into which the defendant had deposited city funds. After the defendant had completed his direct testimony, the state on cross-examination sought to elicit evidence regarding the personal nature of the disbursements made from the account. At one point the following exchange occurred between the assistant state’s attorney and the defendant: “Q. And there is a third marking here, Nick Jamele? A. Yes, sir. Q. He is your bookie, isn’t he, Mr. Ubaldi?” Defense counsel objected immediately. The jury was excused. The defendant moved for a mistrial and took an exception when the trial court denied the motion. Once the jury reconvened, the trial court issued a cautionary instruction to the jury at the request of the defendant. 2
*562 The defendant claims that the implication in the question of the prosecutor that Jámele was the defendant’s bookie was an attempt to introduce inadmissible evidence of bad conduct. This reference to illegal gambling, according to the defendant, not only unfairly prejudiced him in a general sense, but also undermined his credibility, which was crucial to his theory of defense that he lacked the requisite mens rea to commit the crime charged.
The general rule in Connecticut is that a mistrial is granted only where it is apparent to the court that as a result of some occurrence during trial a party has been deprived of the opportunity for a fair trial.
State
v.
DeMatteo,
*563
Upon reviewing the defendant’s first claim of error, we note that the trial court, as a result of its familiarity with the context in which the prosecutor’s remark was uttered, was in a favorable position to evaluate any resultant prejudice. Therefore its determination as to the fairness of the defendant’s trial must be afforded great weight.
State
v.
McCall,
*564 II
The defendant’s second claim of error involves the propriety of certain remarks in the state’s summation to the jury. During its rebuttal the state sought to subpoena Nick Jámele as a witness, presumably to refute the defendant’s statement on cross-examination that certain payments to Jámele were for repairs to the defendant’s house. The defendant advised the court, outside the hearing of the jury, that the witness Jámele would seek to exercise his fifth amendment privilege of silence and requested that the court hear argument and testimony on whether such exercise should be permitted in the absence of the jurors to avoid prejudicing them in any way. The court permitted examination of Jámele outside the jury’s presence. Apparently Jámele was facing federal prosecution for gambling activities and for tax evasion. During the examination the state sought to question Jámele regarding the nature of any construction work done for the defendant, whether Jámele had received money from the defendant, whether the recorded payments were for work done on the defendant’s property, and whether they were reported to federal income tax authorities. The trial court sustained the right of the witness to remain silent in each of these areas of inquiry, thereby foreclosing any examination of Jámele before the jury. The state took exception to each of the court’s rulings, but has not pressed any claim of error in this matter on appeal.
During closing argument the state remarked: “Where is Nick Jámele? Where is the man that he [the defendant] paid six thousand dollars to?” The defendant immediately objected to the comment, but the trial court overruled the objection and allowed the state to continue without any cautionary instruction to the *565 jury. 4 Later, outside the presence of the jury and prior to the jury charge, the defendant moved for a mistrial on the ground that, because of the court’s instruction for the jury to disregard the question implying that Jámele was the defendant’s bookie and Jamele’s successful invocation of his fifth amendment privilege, the state’s request that an unfavorable inference be drawn from the defendant’s failure to call Jámele was improper. The state responded that the remark was a rhetorical question within the proper bounds of summation. When the trial court denied the motion for mistrial, the defendant took an exception to the ruling but did not request that any special instructions be given to the jury.
The state has not attempted on appeal to justify its challenged remarks upon the ground urged in the trial court or on any others. Instead, the state asks this court to apply the due process analysis discussed in part I of this opinion to the closing remarks of counsel and to sustain the conviction because insufficient prejudice befell the defendant as a result. The state argues that our decision in
State
v.
Daniels,
Our review of Connecticut case law dealing with prosecutorial misconduct has failed to uncover a situation precisely like the one before us. 5 In the court below the *567 state first made an inquiry implying some unlawful transactions between the defendant and Nick Jámele, which the trial court instructed the jury to disregard. The state then sought to produce Jámele as a witness in order to prove the unsavory character of his relationship with the defendant. When the court ruled against the state, permitting Jámele to invoke the fifth amendment privilege and effectively depriving the state of such testimony, the state duly excepted to the ruling. Afterwards, in total disregard of that ruling intended to protect the defendant against consideration by the jury of irrelevant and prejudicial matters, the state’s attorney argued that the jury should draw a negative inference from the fact that the defendant had not produced Jámele as a witness.
The prosecutor’s argument to the jury was improper both because the inference sought was clearly impermissible and because it demonstrated a complete disregard for the tribunal’s rulings. 6 The record of the *568 proceedings affords no reasonable inference that this remark of an experienced prosecutor was inadvertent and on appeal the state wisely makes no such claim. 7 Instead, the state insists that this court can only reverse the trial court if the proceedings below, when taken in their entirety, could be deemed to have deprived the defendant of his constitutional right to a fair trial. The ultimate implication of this argument is that a state’s attorney may choose deliberately to ignore any trial court ruling just as long as the state has amassed overwhelming evidence of a defendant’s guilt and the state’s attorney’s misconduct relates to only a portion of that evidence. We decline to place such a restraint on the ability of this court to defend the integrity of the judicial system.

The questions before this court then are whether we should grant a new trial in order to deter prosecutorial misconduct which deliberately circumvents trial court rulings and, if so, whether such authority should be exercised in the circumstances presented.

In Connecticut the appropriate remedy for an unfair trial due to prosecutorial misconduct is to vacate the judgment of conviction and to grant a new trial. See

Some tribunals have declined to use such supervisory power on the theory that society should not bear the burden of a new trial because of prosecutorial misconduct where a new trial is not constitutionally mandated. See, e.g.,

We recognize that the reversal of a criminal conviction in the exercise of a court’s supervisory authority must not be undertaken without balancing other interests which may be involved.

v.
Swan,
We are not today abandoning the due process analysis we have consistently applied to constitutional claims of prosecutorial misconduct not involving purposeful disregard of a ruling, which requires the defendant to prove that he was deprived of a fair trial as the result of the misconduct in order to secure a new trial. Nor are we retreating from our statement that “[cjounsel must be allowed a generous latitude in argument, as the limits of legitimate argument and fair comment cannot be determined precisely by rule and line, and something must be allowed for the zeal of counsel in the heat of argument.”

Pay no heed to it. It is not relevant. It is not significant in the case. It is to play no part in your deliberations.”

State
v.
Perelli,
In criminal prosecutions either the state or the defendant may argue to the jury that an unfavorable inference should be drawn from the absence of a particular witness at trial. Permission from the trial court must be sought in advance when either party wishes to include such an inference in its closing remarks. Such an inference is to be permitted only where “there is sufficient evidence for the jury to find that the absent witness is (1) available to the party against whom the inference is sought to operate and (2) one whom that party would naturally be expected to produce.”
State
v.
Daniels,
The defendant has claimed that although the court denied his motion for a mistrial on the basis of the prosecutor’s inquiry implying that Jámele was a “bookie,” the court in chambers instructed the assistant state’s attorney “that was an area that should be stayed away from if there is no evidence for it.” The state has not challenged this assertion.
