The UK Government and the UK Government alone, should be implementing and enforcing all legislation that governs UK businesses and citizens . Without outside bodies, like the ECHR and previously the EU, being able to override such legislation.
Yes by all means look at what other countries have done, and, if and where appropriate pass similar legislation. And adopt practices that have been proven to be beneficial elsewhere and reject those that haven’t.
But the UK should not have other countries telling it what to do when it comes to enacting its own domestic legislation. (Imagine the UK being able to stymie the law makers in the USA!)
That surely is something that most people would agree with.
