'Call the Midwife' will return to the BBC, despite the show's studios being sold.
Streaming giant Netflix bought the studios where the programme is filmed earlier this year, sparking fears among fans that the series could be axed or rehoused, but BBC drama chief Piers Wenger has insisted the corporation will not be pulling the plug on the Sunday night favourite.
He said: "That show will be made - we're not going to stop making it just because we don't have access to studio space."
Speaking about the lack of funding for dramas as well as the ever-rising cost of producing them, he added: "More generally, of course, it's such a huge problem and lack of availability drives up costs and that is something that we are really feeling the impact of."
The 1950s medical drama has ran for 10 series and last year's Christmas Day special pulled in an audience of eight million.
Piers also opened up about the forthcoming BBC drama about Jimmy Savile, which comes a decade after the disgraced television presenter died.
'The Reckoning' will star Steve Coogan as the sex offender whose heinous crimes only came to light after his death.
He said: "I mean, it is a decade since Jimmy Savile died, it will be a decade next year since his behaviours first came into the public eye.
"But, you know, our primary intention with the drama is to give voice to the victims – to tell their stories sensitively and with the utmost respect. And we have an amazing, award-winning team who are renowned for their factual drama … and I think there are still many important questions that need to be answered about Savile, and many questions that we are asking of ourselves through that drama.
"So I think it’s incredibly important that the BBC, you know, do tell that story."
