Clare's Law 'could have saved my daughter's life'
Clare's Law, which enables people to check the police record of their partners, will be expanded to cover all of England and Wales.
The policy is named after Clare Wood, who was murdered by her ex-boyfriend George Appleton at her Salford home in February 2009.
Her father, Michael Brown - who has lobbied for the law - said it could have saved his daughter's life.
