Identity Documents Bill

If the hon. Gentleman will forgive me, I want to move on to function creep, which is another factor. In evidence to the Home Affairs Committee, the point was made that when identity cards were introduced in 1939—and rightly so in the circumstances of those days—there were three reasons for doing so: conscription, national security and food rationing. By 1950, there were no fewer than 35 stated purposes as to why an identity card was necessary, one of which, incidentally, was the prevention of bigamous marriages. We have not heard an argument in the recent debate that ID cards are necessary for that purpose.
