The 10th season of the BBC One period drama will begin on April 18, after the show's social media pages confirmed the news.

A post from the 'Call the Midwife' Twitter account read: "NEWS!! IT'S OFFICIAL! #CallTheMidwife Series 10 will premiere on Sunday 18th April on @BBCOne!! (sic)"

The show usually airs in the winter but delays to filming caused by the coronavirus pandemic has led to fans being made to wait longer for the latest series of the hit programme, which follows a group of midwives working in London during the 1960s.

The delays meant the show was filmed in the depths of winter with cast members battling freezing conditions on set.

Stephen McGann, who plays GP Dr. Michael Turner, said: "We’ve never filmed in January before, and we’re in this huge cold place. Added to that, the trailers are cold, the set is cold."

He also praised the show's bosses after they were forced to "reconstruct whole scenes" to comply with social distancing guidelines amid the ongoing health crisis.

The 58-year-old actor said: "Acting is a contact sport. The poor old Covid supervisor goes, 'You can’t stand there, you can’t touch them, you’ve got to be here, you’re not allowed to go near here.' And so you have to reconstruct the whole scene. Then our first assistant said, 'Oh, by the way – it’s the middle of summer so you’re all really happy.'"

Stephen also revealed 'Call The Midwife' is running out of diseases to use in storylines with the latest series set in 1966, when vaccination programmes had made significant progress eradicating many illnesses.

He said: "We are actually having a problem on 'Call The Midwife', because we’re running out of these old diseases we started with, because we’re being vaccinated."
