Defendant is charged with prison escape, MCLA 750.349; MSA 28.581, and kidnapping, MCLA 750.193; MSA 28.390. By leave defendant brings this interlocutory appeal from the denial of several pretrial defense motions.
Defendant argues that he was denied his right to a speedy trial because of a delay of over 20 months between arrest and trial. Four factors are considered in the review of a speedy trial claim: length of delay, the reason for the delay, the defendant’s assertion of his right, and prejudice to the defendant.
Barker v Wingo,
It is next contended by the defendant that the trial court’s failure to bifurcate the trial was error. Some jurisdictions recognize that where an insanity defense is alleged together with a defense on the merits, the trial should be bifurcated, because substantial prejudice may result from the simultaneous trial on a plea of insanity and not guilty.
We hold this determination to be within the trial court’s sound discretion. In other states it has been said that the trial court should consider two factors in such a decision: (1) whether defendant has a meritorious defense, and (2) whether there is a substantial claim of insanity related to the incident. Considering the probable expenditure of great additional time and resources, defendant has not shown that such an unusual step is necessary or warranted in this case. See
Sexton v State,
Defendant further claims error in the trial court’s refusal to sever the two offenses for separate trials. The prison escape is alleged to have occurred on March 24, 1973, and the kidnapping on March 26. The trial court concluded that the escape and kidnap were part of the same transaction and that, therefore,

Defendant’s remaining allegations of error are without merit. Accordingly, we remand this cause for separate trials.
Remanded.
