These slides provide an overview of the personal data relationship between the UK and EU after Brexit. Under the Trade and Cooperation Agreement, the UK will have the closest connection with the EU here outside the European Economic Area and Switzerland. This is especially clear in the area of justice and security where there is very extensive provision for data exchange based on common standards. However, in the general area of data protection the framework only points to mutual adequacy. Even with the evolving formulation of this as “essential equivalence”, significant flexibility is retained and this may ultimately result in more substantive divergence than EU-Switzerland given the UK’s more distinct data protection approach. Common bona fide implementation of the Council of Europe’s Data Protection Convention 108+ may provide a good lodestar in the medium term and I very tentatively map out what this may could mean for default standards in the UK related to sensitive data and integrity and also specific substantive restrictions to ensure a more graduated approach and reconciliation with other competing rights.
