CAMPAIGNERS demanded yesterday that the Met Police face a full regulatory investigation for its repeated refusal to hand over personal data on activists.

The Network for Police Monitoring (Netpol) complained to Information Commissioner Christopher Graham that the force was using delaying tactics to delay its legal obligation to tell people if they’re on its “secret surveillance database.”

The group said the Met failed to respond within the legally required 40 days to 70 per cent of subject access requests it received.
