The former DIVA cover star plays one half of the show's
first-ever lesbian couple, alongside Brooke Vincent.
But, in a dramatic cast shake-up, the 19 year-old will be
leaving alongside three other co-stars.
Our insider said: "It's all change at Corrie. We are always
looking to mix things up to keep the show feeling fresh.
"Sacha has decided to do something different, and we wish her
the best. She has been so great in her role as Sian, in the soap's
first lesbian relationship.
"Sacha is a very talented and very young actress. She has her
whole career in front of her."
The other actors to be leaving are: Will Thorp, Holly
Quin-Ankrah and Russ Finton Flynn.
