Information disclosed in court proceedings on Tuesday 11 June is reported to show that the Investigatory Powers Commissioner's Office (IPCO) has concerns about the lawfulness of MI5's handling of people's data, as reported on the BBC.
Commenting on this, Mishcon de Reya Data Protection Advisor Jon Baines said:
"The IPCO has apparently placed MI5 in "special measures" over its use of data gathered under warrants. This may be significant - not just for the current court case - but also because, as Brexit negotiations continue, it could negatively affect any assessment as to the adequacy of the UK's data protection laws. If the UK cannot guarantee the security and privacy of people's data, the European Commission is unlikely to agree to measures regarding transfer of personal data between the EU and a post-Brexit UK. This could have a hugely adverse effect on trade and commerce."
