This is a statement about Nigel Farage’s personal stance — whether he genuinely “disagree[d] fundamentally” — and that kind of internal state is not publicly verifiable. The interview transcript shows that he said the words in that exchange, but that only confirms utterance, not the truth of the underlying subjective claim.
