Judges curtail using or sharing of material, but authorities can examine it for ‘national security’

“A Home Office lawyer said the material seized from Miranda as he was in transit from Berlin to Rio de Janeiro included tens of thousands of classified UK intelligence documents “disclosure of which would risk lives”.

“The Met welcomed the decision “which allows our examination of the material to continue in order to protect life and national security, and for the purposes of the schedule 7 examination [ie whether Miranda is a terrorist].

“Initial examination of the material seized has identified highly sensitive material, the disclosure of which could put lives at risk. As a result the Counter Terrorism Command (SO15) has today begun a criminal investigation. This investigation is at an early stage and we are not prepared to discuss it in any further detail at this stage.”
