Casualty's series producer, who has been with the series since 2019, has announced she is stepping down from the role.
Loretta Preece wrote on LinkedIn that "After nearly three very happy years at the helm of #Casualty I have decided it's time to lay down my scalpel.
"It is a wonderful show bursting with talented and genuine people and it has been my privilege to work alongside them representing the #nhs during this extraordinary COVID period. There are many storylines and episodes that I am enormously proud of but putting #COVID on screen in a way that attracted praise from medics will stay in my memory forever."
During her time on the show Preece also oversaw the long-running show's 35th anniversary, for which a feature-length special set in the past saw the return of Tony Marshall, Charles Dale and Richard Winsor.
Casualty will instead by led by Jon Sen, who was formerly an executive producer on EastEnders and began work on the hospital drama in December.
Meanwhile, Preece confirmed on LinkedIn that while she is leaving the series, she will be staying at BBC Studios and is "very excited" about her new role.
This news comes after Casualty spin-off Holby City came to end last month after 23 years on screen.
The emotional instalment portrayed Jac Naylor's death, which helped "shaped and strengthened" the show's final episode here.
