This seems to be riding on the coattails of the Trump - Russia investigation but in this case, the connection is even less clear. People went to voting booths and voted on the Brexit issue. Neither Arron Banks nor the Russians were in the voting booths looking over their shoulders. This does not seem to be an allegation that Russia hacked the voting process. The story seems to be that a guy met with the Russians who was coincidentally a Brexit supporter.
The connection between the EU and democracy is hanging by a thread. It has three parts, the European Council which is the 28 national governments whose compromise decisions rarely reflect the wishes of anyone, the European Commission which negotiates trade deals, enforces antitrust legislation and proposes legislation and the 751-member Parliament which cannot introduce legislation and has limited control of the budget. The Parliament elects the head of the European Commission who then acts independently.
You can find a previous post of mine where I said that Brexit would be short-term pain for long-term gain. Only the vindictiveness of the remaining countries will tell how much pain that is. But the EU is simply too unwieldy and fragmented to continue as good government and the economically distressed countries are a drain on the finances, so England can just sit back and wait for the inevitable collapse.[/QUOTE]
I think the suggestion is that Banks used funds from Russia to support his campaign. How much of a factor that played on Brexit happening I'm not sure. I think that would be too hard to prove.
Even if there was merit to what you are saying. The problem from a UK point of view is that we now have to go out and make deals with other countries. Something that is already looking like an up hill struggle. Time is ticking against us. We already have a good system in place with the EU. The tricky part of Brexit (or at least the trade side of it) is to keep some form of contact with Europe while striking trade with the rest of the world.
