Mamnoor Rahman was 15 when his father told him and his brother to kill an Oxford Brookes University student who had made his daughter pregnant.
Manna Begum, 20, had been dating 19-year-old Arash Ghorbani-Zarin, an Iranian Muslim who was studying electrical engineering at Oxford Brookes, when she fell pregnant.
This angered her father Chomir Ali, a Bangladeshi waiter, who already had an arranged marriage planned for her.
Mr Ghorbani-Zarin’s body was found with 46 stab wounds in his car in an Oxford suburb in what was described by a judge as a “cold-blooded intentional killing”.
Ali and his two sons - Mamnoor and Mujibar Rahman - were found guilty of murder in 2005, with Mamnoor – now aged 32 – ordered to serve a minimum of 14 years behind bars.
The Parole Board has now decided he is “suitable” for release, subject to licence conditions including living at a certain address with limits on who he can contact, what he can do and where he can go.
A document detailing the decision said at the time of his offending he had “difficulties managing his anger”, a “tendency to brood on particular issues” and a willingness to use violence and carry a weapon.
But since his time in jail he had “come to accept responsibility for the murder”, it added.
He was moved to an open prison in 2017 and “there had been no concerns about his behaviour or compliance with prison rules and licence conditions”, the report said.
A Parole Board spokesman said decisions are “solely focused on what risk a prisoner could represent to the public if released and whether that risk is manageable in the community”, adding: “The panel carefully examined a whole range of evidence, including details of the original crime, and any evidence of behaviour change, as well as understood the harm done and impact the crime has had on the victims.
“Parole reviews are undertaken thoroughly and with extreme care. Protecting the public is our number one priority.”
