The defendant has made twenty-seven assignments of error. We shall discuss one of them.
The defendant argues under his first assignment of error that his guilty plea should be set aside and that he should be tried de novo on the guilt phase as well as the penalty phase of his trial. He says this is so because there was error in reaching the plea bargain by which he pled guilty. In this case, the prosecuting attorney agreed as part of a plea bargain in which the defendant agreed to plead guilty to first degree murder, that the State would present evidence of only one aggravating circumstance, that the murder was especially heinous, atrocious, or cruel. There was also evidence of the aggravating circumstances that the defendant committed the murder while engaged in the commission of a kidnapping and that the defendant committed the murder for pecuniary gain. N.C.G.S. § 15A-2000(e)(5) and (6) (1988).
It was error for the State to agree not to submit aggravating circumstances which could be supported by the evidence. State v. Silhan, 302 N.C. 223, 275 S.E.2d 450 (1981); State v. Jones, 299 N.C. 298, 261 S.E.2d 860 (1980); State v. Johnson, 298 N.C. 47, 257 S.E.2d 597 (1979). The decision as to whether a case of murder in the first degree should be tried as a capital case is not within the district attorney’s discretion. State v. Britt, 320 N.C. 705, 360 S.E.2d 660 (1987). This is so in order to prevent capital sentencing from being irregular, inconsistent and arbitrary. If our law permitted the district attorney to exercise discretion as to when an aggravating circumstance supported by the evidence would or would not be submitted, our death penalty scheme would be arbitrary and, therefore, unconstitutional. Where there is no evidence of an aggravating circumstance, the prosecutor may so announce, but this announcement must be based upon a genuine lack of evidence of any aggravating circumstance. See State v. Lloyd, 321 N.C. 301, 364 S.E.2d 316, vacated and remanded on other grounds, 488 U.S. 807, 102 L.Ed.2d 18 (1988).
*164In order to protect the constitutionality of our capital sentencing system, we must order a new trial. At such a trial neither the State nor the defendant will be bound by the plea bargain previously made. Santobello v. New York, 404 U.S. 257, 30 L.Ed.2d 427 (1971).
We do not discuss other assignments of error because the questions raised under them may not recur at a new trial.
