The Home Office said in a statement on Thursday that the card could be used both as a substitute for a passport when travelling abroad, and also as a proof-of-age card.
Clayton said this could have the de facto effect of making ID cards compulsory, despite government assurances that people would not be forced to have them.
"The thing to worry about is that people will start to demand your card in a pub just because they can — what I call 'petty ID'," said Clayton. "The government says you don't have to carry a card, but actually you do, because you can't do anything without it."
