I don't reckon they'd do much, however there was a lad at my old college who got busted with one and had a court hearing and all sorts, last i heard he ended up with a fine and everyone taking the piss out of him for a few weeks. If your lucky, you shouldn't have a problem. If your not lucky, it might be a fine. The fake passport is definately bad though, if you got busted with that it'd be taken very seriously indeed.
