Turner starred in a live episode of "EastEnders" on 19 February 2010 to celebrate the 25th anniversary of the soap opera. The live episode gained over 16.6 million viewers which saw Stacey's husband die after falling from a rooftop during a police chase before Stacey's confession that she murdered Archie Mitchell. After her co-star Charlie Clements who played her husband left in February 2010, "EastEnders" bosses declared that they are keen to retain Turner after proving her popularity with viewers, however, she announced her decision to leave the show in April 2010. She stated: "I'll miss Stacey and everyone in Albert Square very much but the time has come to try something different." Turner later revealed that she had agreed with Charlie Clements to leave "EastEnders" at the same time as him. Of the decision, Turner said: "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'." She departed on-screen on 25 December 2010.
