"Clare's Law"
Home Secretary Theresa May will announce plans later to introduce a new law to help protect people from domestic abuse, following a campaign by a father from Yorkshire.
"Clare's Law" is named after Clare Wood from Dewsbury, who died after being strangled and set alight by her violent boyfriend. She was unaware George Appleton had a record of terrorising women. Her father Michael Brown led the campaign for Clare's Law which will allow women and men to find out if their partners has a history of domestic violence.
Police will be given the green light to disclose personal information to partners - though not to family and friends - in four areas of the country before the sceheme is extended.
Ninety four women and 21 men were murdered by their partners in Britain in 2010.
