Without being the stick in the mud here, its now pretty much zero tolerance on the whole plates thing, fines and points are being handed out like confetti and they can also pass on your details to the DVLA for them to seize a registration as you appear to not be able to display yours correctly. You then have to re-apply for a reg, as well as gettin your paperwork changed.
The seizure thing is more aimed at the personalized plate thing, but could still apply.
Just a thought
