Rose, J.
After pleading guilty to two counts of sodomy in the first degree and waiving his right to appeal, defendant was sentenced to concurrent terms of 10 years in prison, to be followed by a maximum five-year period of postrelease supervision. On his appeal, defendant primarily argues that his plea was not knowingly entered because County Court failed to inform him at the time of the plea that his sentence would include a period of mandatory postrelease supervision. Although defendant failed to register a timely objection at sentencing or otherwise move to withdraw the plea or vacate the judgment of conviction (see People v. Wehrle, 308 A.D.2d 660, 661), he argues that we should exercise our interest of justice jurisdiction to vacate the plea (see People v. Jachimowicz, 292 A.D.2d 688, 688). We decline to do so, however, inasmuch as defendant did not object at the time of sentencing (see People v. Van Gorden, 307 A.D.2d 547, 548). Likewise, we find no basis for remitting the matter to County Court to give defendant the opportunity to present mitigating evidence regarding the appropriate period of postrelease supervision.
To the extent that defendant's claim of ineffective assistance of counsel calls into question the voluntariness of his plea, it survives the waiver of appeal but is also unpreserved (see People v. Miller, 306 A.D.2d 752, 753). Were we to address this claim, we would find that defense counsel negotiated a favorable plea and provided meaningful representation (see People v. Kreydatus, 305 A.D.2d 935, 936, lv denied 100 N.Y.2d 595).
We have considered defendant's remaining contentions and find them to be similarly unavailing.
Crew III, J.P., Peters, Spain and Kane, JJ., concur.
ORDERED that the judgment is affirmed.
