The issue is that any restriction on freedom needs to be justified, proportionate, necessary and democratic. We need to balance the right to anonymity and privacy with the right to access services etc.
I don't see those problems being any more of a problem here as anywhere else in Europe. Except for the rest of Europe still being rules by the overlords of the eu which is much less democratic per defenition as the eu-elections only choose the one layer off overlords not all of them.
So what problems does it solve, what improvements does it facilitate and what safeguards does it provide against abuse and misuse?
The problem is seems to combat is identity fraud, you could argue it even forces poeple who wouldn't be allowed to vote by their abbusive partner/hushband/fathetr etc. but i think that is wishful thinking.
Safeguards again you tell me what dangerous issues only happen in the uk if they introduce this system? Because it's working fine in other countries, from the last time i went to vote in the uk, they will just need to check your id next to your polling card en then you choose in the polling booth seems safely enough to me.
there are not any more or less voter fraud claims in the uk or the rest of Europe none of which have been proven..
