An MP from the North West is calling for a scheme to help stop domestic abuse to be rolled out across the country.
Government plans to give people the right to ask police about a partner's history were condemned as a waste of money by a leading charity.
The Government is expected to announce "Clare's Law" pilot schemes that will give women the right to ask police about a partner's history.
Police in Greater Manchester have raided dozens of houses, in a search for people suspected of domestic violence.
Officers began their raids before dawn this morning.
It happened on the day 'Clare's Law' was rolled-out nationwide. The law allows women who fear their partner may have a history of abuse, to get a background check from police.
The scheme's named after Clare Wood, who was murdered by her boyfriend in Salford.
The head of a leading charity, which helps domestic violence victims, says a "stronger police response" is needed for such crimes - not a new disclosure law.
Refuge's Chief Executive, Sandra Horley, says 'Clare's Law' may only help "a few women", and do nothing for thousands more at risk of abuse.
Home Office Minister, Norman Baker, says that 'Clare's Law' has succeeded in protecting vulnerable women.
The law is named after Clare Wood, who was murdered by her violent boyfriend in Salford.
The scheme allows those in fear of abuse, or who believe their partner's hiding a violent history, to ask police for a background check.
After a trial in Greater Manchester, women across the country will be able to seek such information from officers.
Step One: Initial contact - police take details on what prompted an enquiry and the nature of a relationship before running initial checks and a risk assessment.
Step Two: Face to face meeting - to gather more information. Police may run checks with other agencies including the prison service, the probation and social services.
Step Three: Multi agency meeting - police meet other safeguarding agencies (such as the probation service, prison service, social services). They decide whether disclosure is lawful, necessary and proportionate to protect a person.
Step four: Potential disclosure - if checks show a record for abusive offences or disclosure would prevent further crime, the police may disclose information to protect a potential victim.
The father of murder victim Clare Wood, says he's "elated" that women nationwide will be able to check their partner's criminal history.

Clare's Law was trialled in Greater Manchester, for 12 months from September 2012, to allow women to check police records to see if a partner has a violent past.
It was named after Clare Wood, who was murdered by her ex-boyfriend George Appleton at her home in Salford in 2009.
She had met Appleton on Facebook, unaware of his history of violence against women including repeated harassment, threats and the knifepoint kidnapping of another ex-girlfriend.
Clare's father, Michael Brown, has campaigned for greater protection for vulnerable women since his daughter's death.
