We cannot just draw a line around these islands and go back to a time past. In 1973 when Britain voted to join what was then the EEC, the email had only just been invented and the Internet wasn't even conceived. In 1992, the Single Market was established and the Internet went commercial. From the mid-1990s, low-cost flights came in and little bags of salad leaves became the norm in our supermarkets. Since then, business has changed to an inter-connected model, underpinned by electronic communications and laws designed to support cross-border trade. Standards matter, not just within State borders, but across borders. The rupture from the Single Market created by Brexit in any form will have massive consequences for industries, both manufacturing and services, that have based their business model on the EU legal framework.

This article - part 1 of 2 - explores the how withdrawing from the EU Single Market will result in a dual-compliance regime. It draws on EU Preparedness Notifications and UK government 'no deal' notices, as well as announcements, media reports and statements from a range of British-based businesses.

Social media companies and content sharing apps could have to foot the bill for a vast automated copyright protection scheme under the most recent EU proposal to update copyright law. For those who remember, this is Hadopi on steroids. It's a proposal that, history tells us, is unlikely to be workable.

The battle over social media content sharing is moving up a gear as the the European Parliament goes for a major vote on new copyright legislation this September. A single, controversial provision in the propoosed EU Copyright Directive has brought the matter to a head in this latest round of the Hollywood vs Silicon Valley conflict. As currently drafted, it could mean that social media platforms and apps would have to restrict content via an automated copyright protection system - dubbed the "upload filter" - and they could be asked to fund the entire system.
