Jimmy’s father Barry revealed that parole statements said Fahri had “done all the programmes” but that “doesn’t seem to have made a blind bit of difference”.

He said: “I think it does strike quite a few questions about the whole [prison] system – what’s the point, you know?”

“I think there’s some questions there certainly for the parole board.”

Asked about the case by LBC, Culture Secretary Lisa Nandy offered her “heartfelt condolences” to Jimmy’s family.

“I think this is a horrendous case, and obviously I think the BBC in particular will want to reflect on the featuring of the person who killed him,” she added.

A spokesperson for Prime Minister Sir Keir Starmer said: “He thinks the BBC needs to answer some questions pretty urgently.

“And obviously I’ve seen that the individual involved has now been returned to custody and his release or otherwise will be a matter for an independent parole board.”

“I reiterate the Prime Minister’s thoughts with Jimmy Mizen’s family who deserve better than to see their son’s murderer shamelessly boasting about his violent crime,” they added.

A BBC spokesperson said: “This individual does not feature on any BBC playlists, we have never played – as we pointed out to the Sun – the lyrics they have printed.

“He’s had two other tracks played twice. 1Xtra has no further plans to play his music, we were not aware of his background and we in no way condone his actions.”
