Coronation Street star Melanie Hill has joined the cast of BBC One's Casualty as Clinical Nurse Manager Siobhan Mackenzie, described as "a no-nonsense team leader who looks set to ruffle a few feathers".
Teeing up Hill's arrival as Siobhan in the new year, the BBC said: "Siobhan is a hardworking nurse, with years of experience, who joins the Emergency Department at a time when the cracks are beginning to show amongst the staff.
"Determined to pull her team together, Siobhan tackles the issues of the ED head-on, using her knowledge and strength to deliver what her department needs."
Hill, who played Cathy Matthews in Coronation Street, said: "I am delighted to be joining the cast of Casualty and I can't wait for fans to meet Siobhan.
"She's a supremely competent manager, who is firm but fair and expects nothing but the best from her nursing team. However, get on the wrong side of her and she'll make mincemeat out of you!
"I'm sure she's going to ruffle a few feathers in the Emergency Department."
Jon Sen, Executive Producer of Casualty for BBC Studios, said he is "so excited to welcome Melanie to the team".
"I've been a huge admirer of her work for years and it's wonderful to see her here at Holby," he continued.
"We've got brilliant stories lined up for Siobhan and can't wait for the audience to meet her."
Hill's many other credits include Waterloo Road, The Syndicate and Bread.
