Speaking on ITV's This Morning today, Marc said: "It will be with a heavy heart that I move on, but it's going to be an experience that I will treasure forever."
Chris Gascoyne, who plays Peter Barlow, is also leaving Corrie this year, leaving fans guessing about whether Peter or Rob will be charged with Tina's murder.
Marc explained: "Chris and I are both leaving at the end of the year, around the same time. This is why we can openly talk about it because it doesn't give anything away. It entices everyone a little bit more. We're trying to keep it as open as possible so it's fortunate that we are both moving on to pastures new."
Will you miss Rob Donovan? I just hope he gets to marry Tracy Barlow first before he leaves as that could be fun to watch.
