A multi million pound prosecution after the murder of the private detective Daniel Morgan collapsed because police lost four crates of evidence.
A joint report between the Metropolitan Police and the CPS described the loss of the boxes as the "final undoing".
Following the withdrawal of the most recent trial into the murder of Daniel Morgan, the Metropolitan Police and CPS have issued their joint review commissioned in March last year.
The trial judge said this case was of an exceptional scale and complexity, with over three quarters of million documents gathered over 20 years being examined.
The issues around the disclosure exercise were such that we could not guarantee that all relevant material had been identified, considered and disclosed so as to ensure a fair trial. A further factor related to the unreliability of critical witnesses.
