Her character Hayley was involved in high-profile storylines, including one concerning a gender transition, and a hostage storyline in the Underworld factory in which Hayley and Carla Connor (Alison King) were kidnapped, bound and gagged by rogue businessman Tony Gordon, who intended to murder them. They escaped unharmed, although Tony was killed in the ensuing explosion. On 11 January 2013, ITV announced that Hesmondhalgh would be leaving "Coronation Street" in January 2014 after 15 years on the show, and that her character Hayley was to leave in a controversial right-to-die storyline, following a battle with pancreatic cancer. She filmed her final scenes on 18 November 2013; they were broadcast on 22 January 2014, the night she won a National Television Award for Best Performance in a Serial Drama, which she shared with her longtime co-star, David Neilson. Over 10,000,000 viewers tuned in to Hayley's final episode, where she ended her life. She worked with pancreatic cancer charities to raise awareness of the disease, and was involved in a petition and attended a parliamentary debate on the subject in 2014.
