I am one of the ~ twelve thousand Brits who like the idea of a national identity card sufficiently to have bought one.
It sat quietly in my wallet, ready to be proffered when entering a Schengen Zone country - just like the citizens of many other EC countries. It also saved me a hell of a lot of time when re-entering the UK, as I could use the IRIS line at border control.
Then along came that infernal busybody, David Cameron, and made an enormous fuss and bother and cancelled the darned thing!
