d) the fact that what was presented as "leave" was an impossible lie
(the cake-and-eat-it option)
e) even if you disregard the cake-and-eat-it faction, both "cake" and "eat it" were under the "leave" umbrella. Doesn't hurt to first settle whether you would prefer "cake" or "eat it" and then hold the referendum.
Oh and of course:
"In a 52-48 referendum this would be unfinished business by a long way." Who said it? Yes, Nigel Farage.
The government spend £9.3 million pounds sending a pro-EU leaflet to every household in the country. That is more than the £7 million campaign spending cap. This is the leaflet in question: https://assets.publishing.service.gov.uk/government/uploads/...
The leaflet doesn't even pretend to be neutral.
I think it is ridiculous to claim that leave overspent+cheated compared to remain. I think both parties played loose and fast with the rules. It just so happens remain is basically in control of the institutions and the bulk of media in the UK so you only really see one side of the story.
