Last Chance for Justice

What if you were jailed for a crime you didn't commit? Panorama investigates the cases of two convicted murderers who have each spent almost 20 years in prison and have always protested their innocence. Their only hope of clearing their names lies with the Criminal Cases Review Commission (CCRC), the body tasked with probing alleged miscarriages of justice. But many believe the CCRC is failing. Reporter Mark Daly finds new evidence in cases the CCRC rejected and investigates whether the watchdog is fit for purpose.
