The push to leave the EU has come from the right in the past 2 decades - the right wing of the Conservatives, and UKIP, made up from people who found the Tories not right wing enough (when founded in the 90s, it did have a few liberal people in it, like its founder Alan Sked, but they were pushed out as it went far right under Farage). And they got plenty of support for that from right wing papers like the Mail, Express and Telegraph.

Farage's rhetoric has never been that of the left. He doesn't talk about bankers (he was, after all, a commodities trader - his best friends are literally bankers; his early prediction immediately after the polls closed on Thursday that Remain had won was based on private exit polls bankers had commissioned to judge the currency markets, and they leaked them to him). Farage talks about a 'struggle' against immigrants from the EU.
