When new clinical nurse manager Siobhan McKenzie walks into Holby this week, she instantly realises the chaotic ED needs a firm hand! First, she lets the junior nurses know who's boss after hearing them gossip about her, before jumping into action and expertly treating distressed schizophrenic patient Scott Baker.

'Siobhan is one of those old-fashioned ward sisters and is there to crack the whip!' reveals ex-Waterloo Road and Coronation Street star Melanie Hill, who plays her. She won't stand for any rubbish from anyone!'
