In its decision summary, the board had said Farhi had initially disputed that the music was “about his own life” but after being recalled to prison, he accepted that he was the artist TEN.

It added that Farhi “needed to reflect” on “why he failed to be open and honest with the professionals managing his case” but this “could be achieved” in an open prison.

Lammy’s reversal has been welcomed by Mizen’s mother Margaret, who told the Sun she was “shocked” by the Parole Board’s initial recommendation.

“I would much prefer this decision didn’t have to be made because he would have turned his life around. I’m really sad that he hasn’t,” she said.

But the reversal shows Farhi had “not changed his attitude”.

“He got into the witness box at his trial and lied through his teeth. Clearly, he hasn’t changed, and I’m glad the justice secretary has seen through it.”

Farhi had been given a minimum 14 year prison term – but, as with all minimum terms, that is the point at which release can be considered, usually with conditions attached about the criminal’s behaviour outside prison.

Music by TEN was showcased on BBC 1Xtra. who were unaware of his real identity at the time of broadcast.
