Star of BBC's Call the Midwife Helen George has discussed the future of the popular show.

George has played nurse Trixie Aylward since the series began back in 2012 when it was originally based on the books by Jennifer Worth and her time as a midwife in the East End of London during the 1950s.

Call the Midwife has since grabbed the attention of global audiences as the latest series 13 airs on BBC.

Now, George has shared her thoughts on what the future of the BBC show could hold and when it might come to an end.

Helen George 'unsure' of the future of Call the Midwife

Call the Midwife's George spoke on the Graham Norton Show with Waitrose over the weekend and discussed the BBC show's future.

Telling Norton: "We’re going into the 70s, because I’ve just started wearing long collars and flared trousers."

However, as Call the Midwife is based on historical events there are concerns that the show could be forced to come to an end.

As George said about the future of the BBC show: "I don’t know is my honest answer. The nuns left the East End in the early 70s. So, historically, there has always been that notion, and that’s the truth of the matter. 

“Whether it goes on to another life form, I don’t know.”

But despite George's concern, Call the Midwife is set to air until 2026 with two more series on the way and Christmas specials.

Sharing more details on the BBC show, George said: "They're going to film again this summer and then next summer."

As Norton said: "You said 'they', has Trixe said goodbye?"

To which George replied: "No, no, not at all, I mean, the company is filming, 'we', the company are filming."

George also commented on the marriage of Trixie and Matthew, played by Olly Rix, sharing "see how long that lasts".

Call the Midwife continues on BBC One and BBC iPlayer.
