Question to the Attorney General:

To ask the Attorney General, what recent estimate his Department has made of the number of cases of forensic manipulation at Randox that resulted in a conviction being overturned; and in how many of those cases had a custodial sentence already been served.

There is an ongoing investigation into data manipulation at Randox Testing Services. The Crown Prosecution Service will continue to support this process to ensure that fairness and transparency in the system is maintained.

The Crown Prosecution Service can only comment on cases that it is responsible for prosecuting. For the cases which it prosecutes, the Crown Prosecution Service does not maintain a central record of the number of cases of forensic manipulation at Randox that resulted in a conviction being overturned or a record of how many of those cases involved a custodial sentence. Such information could only be obtained through a manual search of records which would incur disproportionate cost.
