Holby City has announced the addition of three new characters who will join the show in May 2012.
First to make an appearance on the popular BBC 1 medical drama will be the "charmingly candid and utterly professional" consultant general surgeon Serena Campbell, played by Catherine Russell (The Inspector Lynley Mysteries, Pete versus Life).
Next to join is "cocky and roguish" nurse and transplant coordinator Jonny Maconie (Michael Thomson), who "has no qualms about telling a few white lies to stir up some mischief."
Lastly, Dead Set and Campus star Chizzy Akudolu joins the cast as Jonny's "generous, plain-speaking and warm-hearted" best friend Mo Effanga, who joins Holby as registrar cardiothoracic surgery.
Speaking about the new cast members, Holby City executive producer Johnathan Young told Digital Spy: "These are three very talented actors and I am delighted to welcome them to the cast.
"There are some dramatic and exciting storylines coming up on Holby City over the next few months and I know our new additions will have an immediate impact."
