Patricia Cutts

Patricia Cutts (20 July 1926 – 6 September 1974) was an English film and television actress. She was the first person to portray the character of Blanche Hunt in the ITV soap opera Coronation Street. It would have been her most high-profile regular role to date but after appearing in only two episodes, Cutts was found dead at her flat in Chelsea, London, aged 48. An inquest into her death produced a verdict of suicide by barbiturate poisoning.
