In February 2009, the country was shocked by the murder of Clare Wood.
The 36-year-old from Salford was killed by her ex-boyfriend, George Appleton, who had previously served prison sentences for stalking, harassing and abusing women.
After her death, her family said she would never have entered into the relationship had she known of Appleton’s violent past – and campaigned for a way to alert potential victims of domestic violence of a partner’s prior offences, known as Clare’s Law.
