This law is probably not legal though. The data storage directive wasn't, this probably isn't either. Obviously we have parliamentary sovereignty, so if parliament actually wants it done, then it's the law, but they probably would not exercise parliamentary sovereignty in a case like this which would be dubious treaty-wise once there's a legal judgement against in something like the ECHR. There's a reason this is being considered though, and it's kind of a problem. People probably genuinely believe that unless they can go through stuff that people say, a bunch of the foreigners would cause problems that be dealt with as society is presently organized.
