There was a popular campaign against the government keeping around the hand written, cardboard ww2 National ID cards on civil liberties grounds. They didn't even all have photos, and were super easy to forge! Attlee had kept them around throughout the Labour administration and proposed using them, and this will sound oh so familiar to anyone who remembers the Blair attempts at an ID card and database, as a "a key that could be used to access all the benefits of the state, from rationing to voting to NHS services". The chief Law Lord in the final appeal said of requiring "all and sundry" to produce ID cards that it "inclines them to obstruct the police instead of to assist them".

It was ultimately Churchill's second term that repealed them in the early 50s. The same decade a Conservative politician and lawyer drafted the first European Convention on Human Rights.

Same old arguments, 70 years on. I'm not sure those Tories would recognise today's bunch though. :)
