The mother of a prisoner, who is still in jail 18 years after being given a "cruel and unjust" indefinite prison term, is calling for MPs to back a bill to resentence all 2,734 prisoners in his situation who are still behind bars.
James Lawrence, 37, from Southampton, was given an imprisonment for public protection (IPP) sentence in 2006 for threatening someone with a fake gun.
His mother, Mandy Lawrence, said: "My son has seen murderers come in and murderers go home again, and he's not a murderer. It's ridiculous."
The Ministry of Justice has rejected the idea of resentencing in the interests of "public protection".
