The family of Shabir Choudary who was murdered by his nephew will find out today if probation services could have done more to prevent his death.
Zaheer Aziz, 44, murdered his uncle 27 days after being released from prison in January 2010.
Aziz had been serving an eight-year sentence for attacking two drug users with a scythe and for supplying heroin before he was released on licence.
After Mr Choudary, 52, gave him a place to stay, Aziz killed him with a kitchen knife in his at on Gill Syke Grove, Thornes.
In August last year, it emerged that Aziz could have been sent back to prison before he killed if his level of risk had been properly assessed by West Yorkshire Probation Trust.
Mr Choudary’s family demanded disclosure of the full Serious Further Offence Review into the murder, but West Yorkshire Probation refused, citing data protection and government guidelines
Mr Choudary’s nephew, Nesar Rafiq, called for a change in the law, saying lessons could only be learned if the reports were shared with victims’ families.
Justice minister Jeremy Wright intervened after appeals from the family and local MP Mary Creagh.
He said Probation trusts would have to share a summary report with victims if an offender committed a further serious offence while under supervision.
The rule came into force in April and Mr Wright has asked West Yorkshire Probation Trust to produce a report for Mr Choudary’s family, which they are expected to see later today.
Zaheer Aziz was found guilty of Mr Choudary’s murder in August 2010. He must serve a minimum of 17 years before he can be considered for parole.
