It has been announced that actress Tina Hobley is leaving the BBC One medical drama Holby City after 12 years.

Hobley, who plays ward sister Chrissie Williams, said: "Being a part of the Holby family for the last 12 years has been an experience I will treasure forever but it's time to explore some new challenges."

She continued: "I have loved playing Chrissie Williams but I'm also looking forward to getting my teeth into some other characters and new roles."

The show's Executive Producer, Oliver Kent, said: "As Chrissie Williams, Tina Hobley has been a leading light at Holby City for over a decade and we will be very sorry to see her go."

Kent added: "It has been a joy and privilege to work with her and she has been massively popular with the audience. We wish her all the very best for the future."

Former Coronation Street star Hobley is set to appear in Holby City episodes until November.
