The Duchess of Cornwall has become a strong campaigning voice in recent years for domestic violence charities. While guest editing the Emma Barnett Show, Camilla mentioned her involvement started after hearing one woman’s story at a conference put on by the domestic abuse charity Safe Lives. That woman was Diana Parkes, mother of Joanna Brown who was killed by her violent husband in 2010. After hearing the duchess mention her on air, Diana contacted the programme to tell her story to listeners. She said her two grandchildren, who she took in after their mother was killed, have given her “a purpose in life” Please note: this episode contains discussions of violence and domestic abuse that some listeners may find disturbing.
