Kierston Wareing has admitted it wasn't her decision to leave
The actress, who plays Kirsty Branning, has been written out of the BBC series since new producer Dominic Treadwell-Collins joined and axed four characters.
Kierston told TV Extra she hadn't chosen to leave, but was glad her character was going.
She said: "It wasn't my decision, it was theirs. A new producer came on board and he wanted to shake things up.
"I always wanted them to make that choice. I wasn't really happy with where the storylines were going, because I just thought it has become a bit one dimensional."
Kierston explained that she had struggled with the storyline where Kirsty lies to husband Max that she is pregnant to stop him from leaving her.
She said: "I enjoyed a lot of it, but I didn't really believe what I was doing. In the beginning I did, but I didn't believe the fake pregnancy."
