"Call The Midwife" series nine filming has begun.
The popular BBC One drama series is set to return to screens for a Christmas Special later this year, followed by a further eight episodes to be aired in 2020, and the production company have now started work on the hotly-anticipated next installment.
The "Call The Midwife" Christmas special has already completed filming, and will see the cast take their work to the Outer Hebrides.
Led by Mother Mildred - played by Miriam Margolyes - they embark on a trip to the remote yet idyllic Scottish island chain, where residents have a desperate need for nurses and midwives.
After the Christmas Special, series nine will open with the funeral of Sir Winston Churchill in January 1965, and will continue with Nonnatus House entering a bold and innovative era.
Heidi Thomas, creator, writer and executive producer, said: "After a magical Christmas experience in the Hebrides featuring wild seas, stormy skies and some very disobedient sheep, we return to the harsher reality of city life in 1965. Society is changing fast and in series nine we will see Nonnatus House shaken to its foundations."
The upcoming series - which was created and written by Heidi - follows a triumphant eighth series which averaged nine million viewers per episode, and saw the exploration of many areas of medical and social history, including the impact of disability, adoption, abortion, cot death, intersex representation, cervical smear tests and Sickle cell disease.
The 10th and 11th series of the show have already commissioned, which will keep the programme on air until 2022.
