The security service MI5 has handled large amounts of personal data in an “undoubtedly unlawful” way, a watchdog has said. The Investigatory Powers Commissioner said information gathered under warrants was kept too long and not stored safely. Civil rights group Liberty said the breaches involved the “mass collection of data of innocent citizens”.
