The actress, who plays Stacey Branning in the BBC One soap, admitted that when Clements's character Bradley was killed off in the live episode earlier this year, she knew it was time to go.
She told Fabulous magazine: "Charlie and I always said we'd go at the same time. For quite a while I'd been saying I was going to go and kept realising I wasn't ready. But when Charlie said he was going last year I was like, 'Right, OK, I'm going too'."
Speaking of Stacey's departure, she said: "The whole thing hints at everything she's been through in the last six years and it all comes together. I'm really happy with the way it's all worked out.
"I'd like to be more like Stacey in some ways," Turner continued. "She's so forward and says what she wants to say when she wants to say it. I'd love to be able to be more like that, but I just don't have the guts."
