EastEnders veteran Patsy Palmer is quitting the soap after more than a decade playing Bianca Butcher.
The actress, who is reportedly moving to Los Angeles in a bid to build a career in Hollywood, will leave the BBC1 show this year.
A spokesman for the star said: "Patsy is really sad to be leaving the show as she loves playing Bianca and working with Dominic, but she knows it's the right decision at this time in her life."
EastEnders executive producer Dominic Treadwell-Collins said: "We are so sad that Patsy has decided to leave us, but completely understand that it's the right time for her.
Show bosses have said they will not kill off her character but have stated when she will be leaving: "Bianca won't be leaving Albert Square until the Autumn. We won't be getting rid of Bianca's puffa jacket just yet."
