The e-petition against ID cards on the 10 downing street website has broken the 4000 signatures mark. Only the Repeal the Hunting Bill petition has more. The scale of the opposition to the ID cards plan is being ignored by this high handed government. Head over there and sign it if you can.
NB - the postcode details are only required to show that you live in the UK. I don't beleive that this is any better than asking folks to decalre that they are in the UK (it's not hard to find a UK address to use online). Nevertheless, this is how the website is set up - using a work address or somesuch may make you feel more comfortable!
