Call the Midwife viewers devastated as fan-favourite character quits drama amid fears for its future

CALL The Midwife viewers have been left devastated as a fan-favourite character quit the series.
Fans watched as Nancy Corrigan left Popular for her new life with Roger Noble after not being seen since the start of the series.
The finale of season 14 saw the happy couple depart alongside Collette as Megan Cusack bows out as the nurse.
During the nail-biting episode Nancy went into labour as Roger was by her side while being rushed to hospital.
But they didn't make it in time, as Nurse Phyllis Crane delivered Nancy's baby girl on the way.
Meanwhile, in the same episode young teenager Paula safely delivered her baby, before returning home after placing her baby up for adoption.
Call the Midwife came to a close as Nancy finally married Roger in heartwarming scenes.
Reacting on social media, one devastated fan said: "Well I sobbed and smiled through that finale once again."
A second wrote: "Gutted Nancy is no longer going to be in #CallTheMidwife but I am glad they didn’t kill her off."
"And that's Nancy, Roger, Collette and their new baby girl heading off into the sunset-goodbye and good luck," said a third.
Speaking about her decision to leave, Megan said: "Sometimes, you've got to step out of your comfort zone to grow.
"I've learnt so much, but I'm at the start of my career and I need to take a leap of faith."
Meanwhile, Call the Midwife's future is in doubt, with the drama set to be rested and replaced by a spin-off.
