"If the UK had more lax data protection rules than the EU it wouldn't make a difference. Anyone wanting to do business in Europe has to comply with GDPR no matter where in the world they are based so UK businesses would end up with two different data protection schemes"

And do you want to have less good protection of your personal data? If so, why?
