Well, I discharged my democratic duties around 7am.
Normally this would call for a drink, but even though I had just finished work it was still only 7am, and given what the results may be tomorrow morning, I may need to drink then instead.
It's worth remembering this vote isn't, strictly speaking legally binding. Of course, no government is going to go against it because that would be political suicide, but this does bring up the potential (if unlikely) scenario of there being a dead heat. As the head of the Electoral Commission said, this is an "advisory referendum", so if it's a dead heat, she will declare that. Then the politicians will have to decide.
