Nigel Farage did leave his City/commodities-trading career for politics. High Profiles says he worked as a commodity broker from 1982 to 1986, set up his own business in 1993, and became a founding member of UKIP that same year. Farage’s own biography likewise says he began as a commodities trader and that he "left a successful career" to become a founding member of UKIP in 1993. That contradicts the claim that he had not given up a successful career.
