Queues of trucks, shortages of carrots, but what about our data? We take it for granted to run our lives. It is the invisible agent that enables everything from sending a photo to a friend, to the vast industrial logistics support for those very trucks that deliver the carrots and other vegetables to our supermarkets.

Data-driven activity is so much a part of daily life in 2019 that we don't even contemplate it not functioning. If it didn't function, we wouldn't either.

As we saw in part 1, the ways that Brexit rips through business models are quite complex. Travelling back in time to a simpler era in 1973 before the UK joined the EEC, does not seem like a practical option for business. Cross-border trade, which was the exception back then, is now the norm. People get on planes for one-day conferences and business meetings. The simple email that was conceived inthe early 1970s has itself been outgunned by the smartphone app. Rules are needed to govern these new practices that in themselves generate unforeseen legal complexities. Being outside the EU will not suddenly drop the UK back into a simple system where it can pull up drawbridge and act as an island. There will be too many wires left dangling.

In part 1 of How Brexit Rips Up Business Models, we considered the effects of a post-Brexit dual compliance regime. Here, in Part 2, we look at some specific aspects of Brexit-imposed changes to cross-border trade and trade in services.
