The leavers who voted for the Brexit party did so knowing that the brexit party have said that voting for them is a vote to leave on WTO rules.
No, what they voted for is this;
We have not left the EU. The EU is a democratic union. Therefore, as full current members of the EU we are duty bound to take part in the EU elections.
It is an election to elect your representatives in the EU parliament. So, what the people who have voted for Nigel’s one man band lucky dip party have done is to elect representatives who oppose the existence of the democratic institution called the European Union. Which really when you think about it is a bit silly.
The BREXIT party has no real influence whatsoever as to whether the UK leaves the EU or not, or if it leaves with a deal or without a deal. That is a matter for the UK parliament.
And as I have pointed out, seeing as The BREXIT Party has only two policies.
1. To leave the EU
2. To privatise the NHS
Well, based on that they have two chances of making any impression in a general election.
1. None
2. Fuck all.
