With all respect AC, did that really happen to you, or are you just repeating a viral post doing the rounds from a Labour candidate? It seems incredibly similar!
I'm not sure it's the most essential measure required to protect against voter fraud, the postal voting systems seems far more open to abuse. However voter ID is required throughout most of Europe and even in Northern Ireland for many years, so clearly it can work without being a Tory plot.
In the NHS nurse example - I would like to think a reputable workplace issued photographic ID could be acceptable. Maybe it could be added to the list in future, if this is retained. When I voted, after checking my photo they still asked my address etc, so it's not as if I could just pick up a random person's door pass from work.
