As soon as I hear the word 'brigade' I glaze over.
I don't know what to think about ID cards. I think they could be useful, but wouldn't want them to be linked to health or financial information, and I assume they would be, sooner or later. Name, address, DOB NI and passport number - that sort of thing is fine, and is readily available anyway, but more than that could be dangerous. I'd need more information before deciding if I approve or not.
Also, would people be charged for them? I wouldn't want to see them free for some if others have to pay, and nor would I want to see anyone suffer hardship to get one.
