Georgia May Foote who plays Katy is set to leave the cobbles at the end of the year.
Producer Stuart Blackburn said: “Georgia is a talented actress who has been a great asset to the show. The decision to write out the character of Katy Armstrong is based on storyline discussions and will be one of the consequences of the current drama involving the Windass/Armstrong clan.
“Katy will not be killed off and the door will be left open for a possible return. We wish Georgia every success with her future career.”
