Jessie Wallace, who plays Kat Moon in 'EastEnders', is to leave the series at the end of the year, the BBC has confirmed.
The 33-year-old will exit the soap in an undisclosed storyline, said a spokesman for the programme, adding the decision was "mutual".
She is in talks with the BBC to work on other projects after her departure from the show.
The actress has played the role in the soap since 2000.
Charlotte Avery, who plays Tina Stewart, will also be leaving the Square later this year.
'EastEnders' is hoping to rejuvenate its fortunes with the return of Peggy Mitchell and her sons Grant and Phil.
