The claim that "the classical liberals UKIP picks up believe in individual freedom" is essentially a definitional assertion. Classical liberalism is, by its very definition, a political philosophy centered on individual freedom and liberty. According to the Britannica definition, classical liberalism is "the political-philosophical doctrine which holds that the central problem of politics is the protection of individual freedom or liberty." Merriam-Webster defines a classical liberal as someone who follows "a political philosophy based on the belief that freedom of the individual is paramount." The Stanford Encyclopedia of Philosophy similarly notes that "a liberal is a man who believes in liberty" and that classical liberals specifically link liberty to limited government and private property. Therefore, stating that classical liberals believe in individual freedom is tautologically true — it is the defining characteristic of the ideology. Whether UKIP actually attracts a meaningful number of classical liberals is a separate empirical question (polling data from YouGov and academic analyses suggest UKIP's base was primarily drawn from disaffected Conservatives, working-class former Labour voters, and Eurosceptics, rather than a distinct classical-liberal constituency), but the claim as stated only asserts what those classical liberals believe, which is true by definition.
