Court clears man with severe learning difficulties of 1990 London murder

Oliver Campbell exonerated 30 years after conviction that followed false confessions in police interviews

Oliver Campbell, a man with severe learning difficulties who was jailed for life for the murder of a shopkeeper three decades ago after confessing in police interviews, has had his convictions quashed by the court of appeal.

The judgment clearing Campbell, 54, of conspiracy to rob and murder ends what has been described as one of the longest miscarriages of justice in British criminal history, and will throw a new focus on past policing failures and the current approach of the Criminal Cases Review Commission (CCRC).
