Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what estimate he has made of the number of court cases which will have to be referred to the Crown Prosecution Service to establish if they were affected by compromised data from private forensic drug testing firm Randox Testing Services Laboratory.

This issue remains the subject of an ongoing police investigation to determine how many cases may have been affected and retesting of samples continues at pace. As such, it is not possible to provide an estimate at this time.
