The actress, who rose to fame in the role of teen lesbian Jasmine Thomas in the soap Emmerdale, will star alongside Matt Smith’s timelord in the BBC series.
Coleman’s Doctor Who debut will be in the Christmas special after Matt Smith’s current companion Amy Pond (Karen Gillan) has made what writer Steven Moffat describes as a “heartbreaking” exit in the fifth episode of 2012.
Coleman’s other TV credits include ‘Waterloo Road’, in which she played disruptive sixth form pupil Lindsey James. She will also appear soon as Annie Desmond in Julian Fellowes’ new ITV1 Titanic drama.
