Was going to say here is a positive of Brexit. The new Data plans that are getting unveiled that were not possible in EU.
But i am sure Chopley will say that was always possible or find some negative to it. Surprised he never mentioned it in the thread but i guess only negatives he looks for.
Here is the Governments take on it tho all the papers have their say as well.
Where to even start with all the problems with this policy, and this is actually on my own patch now
In essence conformity to the highest and most widely recognised standards are what matters in this field, so any sort of 'lightweight' standard just gets ignored. (For a very recent comparison point, look at the UK Gov deciding not to implement our own UK kitemark to replace the internationally recognised EU CE standard, when it became clear that no one in the UK wanted it and no one internationally would recognise it.)
Many UK datacentre hosting companies have already, without fanfare and without fuss, moved some datacentre capacity to the EU (Dublin is a favourite location, they've been very happy there), this will simply accelerate that process.
The EU isn't going to allow a 'have your data cake and eat it' approach from the UK, so as we diverge from the EU/GDPR you can bet we'll lose our 'data adequate' status, which will further incentivise UK operations to move to the EU so that they can comply with the highest standards, whilst also remaining 'backwards compatible' with what will then be our lower standards.
There's actually nothing the EU would like more than us shooting ourselves in the foot again to increase costs and complexity for British businesses looking to do business internationally, (
which will still need to abide by GDPR unless they just want to sell British apples in Telford), as the EU will harvest the benefits. Many in the EU would be quite happy for the UK to erect its own data law barriers to UK tech firms and other service providers, which won't garner any sort of international recognition or importance - GDPR will continue to be king in this field.
Basically, you know all those stories that are being run now with how UK importers and exporters are having a torrid time doing business on the international stage and particularly with the EU, and how a lot of them have set up operations, warehousing and distribution in the EU to get around it? It'll be like that again but with data.
TL: DR - GDPR compliance will continue to be a thing on the international stage, and businesses (including in the UK!) will continue to uphold and adhere to those standards, the UK going rogue with its own small scale scheme won't gain any traction at all, and will just add further inconvenience, red tape and costs to UK Plc that really, really isn't interested.
(What it will do however, is open up your data being sold far and wide to whoever wants it, US style, so there's that, I guess. The 'UK Citizen' database will be quite valuable to various corporate interests, and you won't have the protections of GDPR.)
