It is a matter of public record that British citizens have worked at the European Commission — the EU institutions employ nationals from all member states, including the UK. That basic factual element is not in dispute. However, the core of the claim is the characterization of unnamed British Commission staff as "fanatics" who "hate this country, everything it is and everything it's ever stood for" and are "filled with self-loathing." The term "fanatic" is inherently subjective and pejorative. Farage does not name any specific individuals, and there is no objective, publicly available standard by which one could verify whether unnamed civil servants qualify as "fanatics" or measure their degree of patriotism or self-loathing. This is an opinion dressed as a factual claim — it reflects Farage's personal characterization of people he perceives as overly enthusiastic about European integration, not a verifiable assertion about the world. Public sources show Farage has repeatedly used the term "fanatic" to describe various EU figures (e.g., Martin Selmayr, Guy Verhofstadt, Ursula von der Leyen), but these are his own rhetorical labels, not independently corroborated characterizations. No public evidence independently confirms that British Commission staff meet an objective definition of "fanaticism." Since the claim rests on a subjective characterization of unnamed individuals' beliefs and attitudes — information that is not publicly available and cannot be corroborated or contradicted by public evidence — it falls into the "not-enough-evidence" category.
