Figen Murray on how forgiving her son's killer has preserved her humanity

Marina Cantacuzino talks to Figen Murray about what forgiveness means in the context of losing a child in a terrorist attack. In May 2017 her son, Martyn Hett, was killed at the Ariana Grande concert in Manchester when a radical Islamist detonated a homemade bomb.
