CALL the Midwife's Sister Julienne star has issued a warning to fans amid mounting fears the show will be axed.
The latest storyline on the BBC One period drama has unnerved fans who are 'terrified' the show will come to an end.
It saw the health board pay an unexpected visit to Nonnatus House during Sunday's episode, where bad news was delivered.
And now Jenny Agutter, who plays Sister Julienne, has warned the show cannot continue forever.
She said: "We are bound by the years though, because of this thing of it being grounded in research and the time."

She continued to tell Express.co.uk: "The '60s were a very particular time of change and it is wonderful looking at that, it will be interesting to see how, if it went into the '70s what would happen.
"Because it would have to be completely different, so I mean, I have always felt we have taken it year by year."
Meanwhile, Cliff Parisi, who plays handyman Fred Buckle on the show, made it clear he wants the series to continue forever.
But he did admit: "It will go on as long as Heidi and the BBC want to carry on making it and if one day they decide it's over, it's over.
"And we will all go off and do something else I am sure but at the moment we are all devoted."
During the recent episode, Sister Julienne was told by the health board: "Nonnatus House is financially inefficient and too dependent on the resources of the Turner practice which we also have in our sights.
"You both use dangerous unskilled labour for maintenance. Finally, and I shudder to think how things have come to such a pass in the modern age, you are currently only operational because of private charity."
Call the Midwife airs Sundays at 8pm on BBC One and iPlayer.
