Joanna Michael murder: Ministers to review case
The case of a woman murdered by her boyfriend after a 999 delay will be referred to ministers, House of Commons leader William Hague told MPs.
Joanna Michael, 25, from St Mellons, Cardiff, rang 999 twice before Cyron Williams stabbed her to death in 2009.
The Independent Police Complaints Commission (IPCC) ruled she was failed by south Wales and Gwent police forces.
Caerphilly Labour MP Wayne David told MPs the Supreme Court had ruled a negligence claim could not be brought.
It comes after Ms Michael's mother told BBC Wales' Week In Week Out programme she would take her daughter's case to the Westminster to get "justice".
"Can we have a debate with a view to a change in the law so that the police are held to account in the same way as doctors, teachers and the armed forces?" he said.
Mr Hague said it was a disturbing case and he would refer it to his ministerial colleagues, including those in the Ministry of Justice.
"I will ensure that the matter he has raised is now looked at by ministers," he said.
Mr David is backing Ms Michael's mother, Angela, in a campaign for a change to the law which protects police forces from negligence claims.
Ms Michael's parents, her son, six, and daughter, 12, won the right to try to bring a claim in 2011, but it was later thrown out.
Williams was jailed for life in March 2010 after admitting murder in a "frenzied" attack.
