Britain to introduce compulsory digital ID for workers

You don't really need that - you can stand on the beach and watch.

The issue is more with the laws - we have human rights laws where you can claim asylum and a very slow and expensive legal system where almost no one actually gets send back. What the government should do is change the laws to something that agrees more with common sense.
