Scott & Bailey star Suranne Jones is to play the lead role in a new BBC drama called Doctor Foster.
Written by Mike Bartlett (King Charles III, The Town, Chariots Of Fire), the series follows GP Gemma Foster, whose world is turned upside down when she suspects that her husband Simon (Bertie Carvel) is having an affair.
Jones said: "I loved Mike Bartlett's work before, King Charles III was really stunning and now I have this wonderful script that deals with very 'human' issues from marriage, motherhood, family, loyalty, pride, betrayal, and the very delicate subject of age."
She added: "It's about looking at one woman's story and asking, 'What if that was me? What would I do in that situation?' And the age-old question of why. I am very much looking forward to telling Gemma Foster's story.''
