potentially the most problematic aspects of Brexit are not the big issues but the small technical details: too small to merit day-to-day attention but too important to be left to float on the tides of the Brexit seas.

One such issue is potentially data transfers between the UK and the EU after Brexit. Although not as immediate or striking as the Irish border issue, nor as politically engaging as the issue of devolution and Brexit this has the potential to derail UK trade post Brexit across every sector of the economy from finance to manufacturing by way of education, agriculture, and media and entertainment. The reason for such a potentially catastrophic outcome is because as first observed by Clive Humby, the architect of Tesco’s Clubcard scheme, in 2006 and oft repeated since, “data is the new oil”.
