I’d love to think that the Leave vote was influenced by nefarious foreign machinations, but just like Trump’s election, clearly it wasn’t. Unless the £350m a week for the NHS on the side of a bus (more funding for public services was apparently a significant factor in Leave voting) was Putin’s idea. They probably have tried a bit, and certainly gave money to Banks and Farage, but I just don’t believe it had a significant impact. And even if it did it isn’t provable. I think that there were enough people who had genuine issues with the EU, and a lot more who don’t like their own lives and were conned by our very own home grown charlatans into thinking that leaving would make them somehow better.
The Russians are of course delighted with the mayhem created by the result though.
