Any political system is a compromise between efficiency and legitimacy, balancing a government's ability to act against the certainty that its citizens support the government's actions. So says Against Elections: The Case for Democracy*, a book I first read a few years ago but which I have been reminded of ahead of the UK elections on the 12th December.
The UK selects its Parliamentary representatives through a First Past The Post electoral system which errs on the side of efficiency (it reliably produces governmental majorities, recent history excepted), but perhaps with a loss of legitimacy (there hasn't been a party winning more than 50% of overall votes since 1935).
Meanwhile a key factor in the election is the Brexit referendum. We can all agree that referendums aren't an efficient way to govern a country, but the legitimacy of the Brexit referendum is in the eye of the beholder. Some argue that it is the UK's most legitimate political result in living memory, voted for by 17.4 million people (more than have ever voted for a single political party in a General Election). While others question its legitimacy on grounds of misinformation (based on what we know now) or technicality (it's not legally binding). One thing which is clear is that our Parliamentary system is not designed to deliver on the outcome of referendums if there is ambiguity involved, and I don't know if this election will change that.
Regardless, according to Jean-Jacques Rousseau, we are currently living in a rarefied period of time:
“The people of England regards itself as free; but it is grossly mistaken; it is free only during the election of members of parliament. As soon as they are elected, slavery overtakes it, and it is nothing.” ― Jean-Jacques Rousseau, The Social Contract
That seems a little drastic to me. But either way please remember to vote on December 12th.
* More broadly the book talks about the mistaken conflation of elections and democracy, proposing a deliberative democracy alternative, but that's not for now.
