Jennifer Kirby is to leave the cast of Call The Midwife after four years.
Jennifer has been playing Nurse Valerie Dyer since series 6 in 2017.
However she won't be a part of the upcoming tenth series, announcing her exit in a post on social media.
Jennifer wrote: "After four joyful years spend with Call the Midwife I have decided to say goodbye to Nonnatus, Val and the wonderful cast, crew and production team.
"The programme is truly a national treasure, and it will always be a huge honour for me to have been a part of something so wonderful. I can't wait to keep watching our beloved Nonnatuns from the other side of the screen.
"Long live Call the Midwife. So long chicks. x"
