The defendant’s probationary sentence was revoked at a hearing during which he was not offered or represented by counsel.

Mempa v. Rhay (1967), 389 US 128 (88 S Ct 254, 19 L Ed 2d 336) requires that the court advise one accused of probation violation of his right to be represented by counsel and, if indigent, to the appointment of assigned counsel if the violation hearing includes sentencing. That holding applies retroactively. McConnell v. Rhay (1968), 393 US 2 (89 S Ct 32, 21 L Ed 2d 2); People v. Marshall (1969), 16 Mich App 578.

The revocation of the defendant’s probation and sentence to prison is set aside and the cause is remanded for a hearing on the probation violation charge at which the defendant shall be advised of his right to be represented by counsel and, if indigent, to the appointment of assigned counsel.
