Suranne Jones (born Sarah Anne Jones; 27 August 1978) is an English actress. She first rose to prominence playing the role of Karen McDonald in ITV1’s soap opera Coronation Street over a period of four years. In 2004, she left Coronation Street, later remarking: “I just thought, while [Karen]’s brilliant and I’m enjoying her, I’ve got to get out”.
Upon leaving, Jones took on roles in many drama series broadcast on ITV1 and BBC1, such as Vincent, Strictly Confidential, Unforgiven, Five Days and Single Father, whilst also appearing in various theatre productions, earning her critical acclaim, described by Andrew Billen of The Times as being in a category of “those brave, talented few who earn their wings on a soap and then fly gloriously beyond it”. In 2011 Jones starred in Scott & Bailey as DC Rachel Bailey, with the television series being an original idea conceived by Jones herself and fellow actress Sally Lindsay.
