A show insider said : "Charlie's very popular among the cast and he'll be missed. His character has made a big impact over the last year, quite ground-breaking really - no doubt there will be a juicy exit for Marcus. The likelihood will be a love triangle." Speaking of his departure Condou said: "I have had a fantastic time in Coronation Street, but as a jobbing actor I believe it is time to move on. There are a few things in the pipeline, one of which is a feature film which is being made abroad. But all that's under wraps at the moment." A Corrie spokeswoman said : "We'll be sad to see Charlie leave. The decision was a mutual one." In January 2011, it was confirmed that Dent would return to "Coronation Street".
