ITV have confirmed that Katherine Kelly will leave Coronation Street next year, the exact details of her exit are as of yet, unknown.
I personally am happy she is leaving, when Becky came into the show, she was interesting and unpredictable, when she moved in with the Croppers, she became lovable.
When she moved into the Rovers, she then became repetitive and boring. Constantly messing up Steve's life for her own gain, I hope we see a spark of the original Becky when she goes.
