I also disagree with his statement at 30:50 where he claims that Donald Trump and Nigel Farage are trying to fix what they see ailing democratic capitalist societies. Farage quit as soon as Brexit referendum was held, he just wanted to destroy everything and not participate in the mess he created.
For what it's worth, just wiki'd Lafarge, in the 2015 election he didn't win his seat so he resigned as leader as he had promised, but the party didn't accept it so he stayed on for another year, then resigned again after brexit vote. Not sure what use he could have been organizing the Brexit by not only not being part of the government but not having a seat/vote in Parliament. I guess he can mouth off in his private life just as easy.
