The idea was suggested by Labour some time ago but basically unpopular in the wider population.
but its true to say all the illegal migrants coming from france ( where there is ID cards like much of europe) are doing eveything they can to get to uk not only because of better economic prospects, but because there is no ID cards so very difficult to track them when they arrive. they tend to merge into immigrant communities such as islamic ones that are very closed off and good cover for them and they dont look to take benefit but to work illegally
I myself an immigrant with a long term visa have documentation to show my right to be here, but is it time everyone carried a card to show their right to be here?
