Jessica Raine has said it was a privilege to star in Call The Midwife.
The actress bowed out of the BBC One period drama at the end of series three, with her final scenes as midwife Jenny Lee airing last night as her alter-ego took up a nursing post at a Marie Curie cancer hospital after growing dissatisfied with midwifery.
Jessica said in a statement: "It's been a real privilege to help bring Jenny Lee's story alive and amazingly satisfying to see how the public have embraced the series, but as is in keeping with Jenny's story, it's time for me to explore pastures new.
"So it is with a head full of wonderful memories that I leave my friends and a show that I know will continue to go from strength to strength."
The actress might have already landed a role in new Sky Atlantic drama 'Fortitude' opposite the likes of Sir Michael Gambon, but she insists she won't forget her former co-stars and will be tuning in to every episode of series four in 2015.
She added: "I, too, will be tuning into series four and blubbing with the nation."
Meanwhile, a spokesperson for the show confirmed that Vanessa Redgrave, who voices a more mature Jenny, will continue on as narrator.
They said: "'Call the Midwife' will carry on with that fascinating and emotional story, celebrating the people of Poplar, and the much-loved residents of Nonnatus House.
"Vanessa Redgrave will continue as narrator, maintaining our link with the very special author of the books that inspired us.
"We wish Jessica all the love and luck in the world as she cycles off into her future."
