Kym confirmed the news in a statement, which said:

"When I was lucky enough to be offered four episodes on Coronation Street, I could never in my wildest dreams have thought I’d be here thirteen years later

"It’s been an incredibly difficult decision but it feels like the right time for me to take a break from the show and explore some other roles.

"But this isn’t the last you’ve heard of Michelle Connor, she’ll be back! I can’t wait to see what the writers have in store for the future."
