You are correct about voting eligibility and expats and I equally share your stance upon that. We just don't know and given the checks (lack of) involved, may never know. Had we had a national ID card, such systems might take on more credibility, alas such ID cards in the UK are often disdained by a vast majority for various reasons of self-privacy. Yet such ID cards are most common throughout Europe. Indeed, some countries (Brussels iirc as one) have a law that makes not voting in an election a crime, so they get close to 100% turnout, they also have ID cards.
