Re: I'm waiting ...
Since 1860 the numbers have been recorded to resolve any suspicion of voter fraud, but there have been instances in the past of, say, votes for Communists being traced and logged by MI5. Whether the state could and would find a way to trace and catalogue tens of millions of votes in the 366 days before the ballot papers have to be destroyed is another question.
Let's face it, Tory voters, you're probably safe from being investigated by MI5. Historically, though, every other political group of any durability has been under suspicion at one time or another. Well, except possibly the Monster Raving Loony Party.
