I cannot imagine that anyone on the Continent cares two hoots whether one has a GB or a UK sticker. It only serves to allow the country where the vehicle is registered to be identified, in particular if a traffic offence has been committed. After decades of being used to GB the origin of a vehicle displaying it should be abundantly clear. Indeed, I reckon that quite a lot of people on the Continent are now scratching their heads, asking themselves where that funny UK identifier originates from. The Ukraine perhaps? UK doesn’t readily mean anything to anyone abroad.
