How would we take control?
Through alliances with other Right Wing parties. European elections are almost always good for Right wing votes. Its how initally UKIP, and then the Brexit Party, established a foothold.
And lets say we rejoin. There would naturally be an anti-EU party emerging. Be easy to stir up people to vote for it once more. Join those votes in the European Parliament with those of the AFD and the Front National and the Brothers of Italy, along with all the other Right Wing parties, and suddenly its a huge voting block.
My/our desire for a genuine Right Wing party is never going to materialise. Even with a majority in Parliament it would face the entire judicary and civil service doing everything to scupper it. Ditto with the Royals.
We need to start thinking in a far bigger way. Otherwises it is just going to be a waiting game until it all implodes under its own contradictions. And that is going to be very messy.
But if we take control of the EU...then we get to make our own laws. And the UK will then have to implement them. That's the point. The UK establishment have us in a trap. We need to change the game.
