Harris family's Corrie exit revealed?
The storyline - one of Coronation Street's most sensational ever - will kick off when Katy reveals she expecting the baby of her older lover, Martin Platt.
The pair become involved in a huge row which ends with Katy - actress Lucy-Jo Hudson - knifing Tommy. Martin is the prime suspect for the murder but Katy's mum Angela then tries to take the blame.
The plot marks the long-anticipated departure of the Harris family from the soap. Only son Craig, played by 15-year-old Richard Fleeshman, will remain.
